# Colour-Blind-Safe Chart Scheme Drafter

A reusable prompt that turns your own data-series list into a colour scheme with redundant cues, contrast notes and a text-label fallback.

## Start here

This is a reusable prompt for an ordinary AI chat that accepts text. It helps you draft colours and redundant cues for a chart you will build yourself.

**What to paste:** a list of your data series, one per line. Each line is a series label; you may add a short note about what it represents or how it relates to others. Optionally add chart context: chart type, background colour, printed or on screen, and any colour you must keep.

**Where to paste it:** into your usual AI chat together with the complete prompt text supplied below. No terminal, no account setup and no API key are needed.

**How to check the output:** the reply should first confirm how many distinct series it found, then give a colour table with columns `Series | Hex | Description | Redundant cue | Contrast note`, followed by a pairwise caution list, a text-label fallback per series, and a closing boundaries line. Confirm that every series from your list appears exactly once, that each has a cue surviving black-and-white printing, and that weak pairs are named with a fix. If a series is missing, a cue depends on colour, or a hard-to-separate pair is unflagged, treat the draft as failing and ask for a fix.

**Known defect in the supplied source prompt you must watch for:** in the source's fictional mini example, only four series are listed (reach, clicks, spend, conversions), yet its "Illustrative output shape" and "Check against my example" sections say five rows and "all five series appear". That internal self-check cannot be satisfied by the example as written. The prompt text is preserved unchanged as the original, so ignore the "five" count when it contradicts your own list: the only count that matters is the count of series you actually paste. Readers who need a clean example can mentally correct "five" to "four" for that fictional block.

**What the assistant still cannot know:** it cannot see your data values, group membership beyond what you typed, your charting tool or your final rendering. If you give no background colour, it will assume white and say so.

## Introduction

Colour alone is a fragile way to separate data series, especially for readers with red-green, blue-yellow or low colour vision. This prompt asks the assistant to pair each series with both a colour and a non-colour cue, such as line style, marker shape, a direct label or a fill pattern, and to flag pairs of series that are hard to tell apart. The output is a written design draft you apply yourself in your own charting tool.

## Prerequisites, setup and permissions

- A text-based AI chat you already have access to; nothing else is required.
- Your own series list: one line per series, optionally with a short note about what the series represents or how it relates to others.
- Optional chart context: chart type, background colour, print or screen, and any colour you must keep.
- No file access, integrations, background actions, paid capabilities or credentials are involved. You stay in control of what is pasted, so avoid confidential series labels if your chat account does not allow them.

## What a correct output checks

1. A series count line matching your own list, plus any open questions instead of silent guesses.
2. A colour table where every series appears exactly once, each row having a hex code, a plain-language description, an explicit non-colour cue and a contrast note.
3. A pairwise caution list naming the pairs most likely to be confused, each with a one-line fix.
4. A text-label fallback giving each series the shortest label that identifies it in a monochrome version.
5. A boundary line stating these are design suggestions to be verified in your own tool and with a colour-blindness simulator.

## Limitations

- This is a design draft, not a rendered chart. Nothing here has been executed or rendered by the assistant.
- Contrast notes are advisory; with no background supplied, the prompt assumes white and says so.
- The assistant cannot see your data values, open your charting tool or apply the colours for you, and it must not claim accessibility certification.
- The supplied source prompt contains the four-versus-five example-count defect described above; this is an artefact of the original text, not of your data.

## FAQ

**Do I need special software, a terminal or an API key?** No. Any AI chat that accepts text is enough; the prompt produces only a written draft that you copy into your own design work.

**What if my series list is empty, or two series share a label?** The prompt tells the assistant to ask you for the list, or to ask you to distinguish duplicates, instead of guessing. It also must not silently add, drop or merge a series.

**Is my pasted content private?** The prompt itself runs inside whatever chat account you use, so its handling depends on that provider; do not paste confidential labels if your account settings do not allow it.

## Verification note

source reviewed; runtime not tested.

## Complete reusable prompt

# Colour-Blind-Safe Chart Scheme Drafter

You are helping me choose colours and redundant cues for a chart I will build myself. I am pasting a list of data series below. Work only from that list. Do not invent data values, group membership, labels or extra series.

## What I will provide

I paste a list with one line per data series, in this shape:

- Series label
- Optional: a short note about what the series represents or how it relates to others

Optionally I may also paste my chart context (chart type, background colour, whether it will be printed or shown on screen, and any colour I must keep).

## Your task

1. Read my series list and confirm how many distinct series you found. If any line is ambiguous, ask me one question instead of guessing.
2. Propose a colour scheme in which no two series rely on hue difference alone. Aim for differences in lightness as well as hue, so the set still separates for people with red-green, blue-yellow or low colour vision.
3. For each series, give a candidate colour as a hex code, plus a plain description. Where I must keep an existing colour, work around it.
4. For each series, add a redundant cue that does not depend on colour: line style, marker shape, direct text label, fill pattern, or a short in-figure tag. Give the cue explicitly.
5. Note the contrast between each colour and my background. If I do not specify a background, assume white and say so. Where a colour-versus-background or colour-versus-colour contrast is weak, flag it and offer an alternative.
6. Produce a short fallback plan: if the colours still fail for a particular reader or output, what text label, ordering or annotation makes each series identifiable without colour.

## Output format

Return these sections, in order:

- **Series count and questions**: the number of series, plus any open questions.
- **Colour table**: columns `Series | Hex | Description | Redundant cue | Contrast note`.
- **Pairwise caution list**: pairs of series you judge hard to tell apart, with a one-line fix for each.
- **Text-label fallback**: for each series, the shortest label or annotation that would identify it in a monochrome version.
- **Boundaries**: one short line stating that these are design suggestions and that I must verify the final chart in my own tool and with a colour-blindness simulator.

## Uncertainty and missing input

If my series list is empty, ask for it. If two series share the same label, ask me to distinguish them before continuing. If I give no background colour, state the white-background assumption in the contrast notes. Do not silently add, drop or merge a series.

## Review checks before you finish

- Does every series in my list appear exactly once in the table?
- Does every series have a cue that would survive a black-and-white print?
- Are there any two rows whose hex codes differ mainly in hue, with near-equal lightness? If yes, fix that pair.
- Have you avoided saying anything about how the chart will render in a specific product?

## Boundaries

This is a design draft, not a rendered chart. You cannot see my data, open my charting tool or apply these colours for me. Do not claim accessibility certification. Tell me clearly when a judgement is uncertain.

## Fictional mini example of the input style

- Ad reach
- Ad clicks, note: always lower than reach
- Ad spend
- Ad conversions
- Background: white. Chart: grouped bar.

## Illustrative output shape (not real values)

A table with five rows, each with a hex code and a description such as "mid-dark blue", a redundant cue such as "solid fill plus direct end label", and a note such as "strong against white; keep when printed". Then a pairwise caution list naming reach vs clicks and clicks vs conversions, each with a fix. Then one short text-label fallback per series, e.g. "Reach", "Clicks", "Spend", "Conv." Do not treat these shapes as final content: derive the real rows and cautions from the series list I supply.

## Check against my example

For the fictional list above, pass if: all five series appear; no two series are distinguished by hue alone; every row has a printable cue; weak pairs are named with a fix; and a monochrome reader could still tell reach from clicks from spend from conversions from the labels alone. Fail if any series is missing, if a cue depends on colour, or if a pair is left unflagged when it is hard to separate.

# 色盲友好图表配色方案起草提示词

一条可复用提示词：把你自己的数据系列清单转成一套配色方案，包含冗余线索、对比度说明和每个系列的纯文字标签备用方案。

## 开始使用

这是一条可复用提示词，适用于任何能接收文字的普通 AI 对话。它帮助你为自己要制作的图表起草配色和冗余线索。

**粘贴什么：** 你的数据系列清单，每行一个系列。每行是一个系列名称，可以附一句关于它代表什么或与其他系列关系的简短说明。还可以补充图表背景信息：图表类型、背景颜色、用于打印还是屏幕显示，以及任何必须保留的颜色。

**粘贴到哪里：** 粘贴到你平时使用的 AI 对话中，并附上下面提供的完整提示词文本。不需要终端、不需要配置账号，也不需要 API 密钥。

**如何检查输出：** 回复应先确认找到多少个不同的系列，然后给出一个颜色表格，列为 `系列 | 十六进制色值 | 描述 | 冗余线索 | 对比度说明`，接着是成对警示清单、每个系列的纯文字标签备用方案，以及最后一段边界说明。逐项确认你清单中的每个系列都只出现一次，每个系列都有能在黑白打印下存活的线索，且薄弱组合被点名并给出修正方法。如果有系列缺失、某个线索依赖颜色，或者某对难以区分的组合未被标注，应判定草稿不通过并要求修正。

**原提示词中需要注意的一处缺陷：** 在来源的虚构小示例里只列出了四个系列（“广告触达人数”“广告点击量”“广告支出”“广告转化量”），但它的“示意性输出形态”和“对照我的示例检查”两节却写“五行”和“五个系列全部出现”。就示例本身而言，这个自检无法通过。提示词原文为保留原始内容，未做改动，所以当“五”这个数字与你自己的清单矛盾时请忽略它：真正重要的只有你实际粘贴的系列数量。如果你需要一个干净的例子，可以在心里把那个虚构块里的“五”改成“四”。

**助手仍无法知道什么：** 它看不到你的数据数值、你输入之外的分组归属、你的制图工具或最终渲染结果。如果你没给背景颜色，它会假设为白色并说明这一点。

## 简介

仅靠颜色区分数据系列是脆弱的，对红绿色觉、蓝黄色觉或低色觉的读者尤其如此。这条提示词要求助手为每个系列同时配一个颜色和一个非颜色线索，例如线型、标记形状、直接标注或填充图案，并标出难以区分的成对系列。输出是一份文字设计草稿，由你在自己的制图工具中应用。

## 前提、设置与权限

- 你已能访问的一个文字型 AI 对话，除此之外无需其他条件。
- 你自己的系列清单：每行一个系列，可附一句关于该系列代表什么或与其他系列关系的简短说明。
- 可选的图表背景信息：图表类型、背景颜色、用于打印还是屏幕显示，以及任何必须保留的颜色。
- 不涉及文件访问、集成、后台操作、付费能力或凭据。粘贴内容由你控制，如果账号设置不允许，请避免粘贴机密系列名称。

## 正确的输出应检查什么

1. 一行系列数量，与你的清单一致，并对疑问提出询问，而不是默默猜测。
2. 一张颜色表格，每个系列只出现一次，每行包含十六进制色值、通俗描述、明确的非颜色线索和对比度说明。
3. 一份成对警示清单，点名最可能混淆的组合，每对附一行修正方案。
4. 一份纯文字标签备用方案，为每个系列给出能在单色版本中识别它的最短标签。
5. 一行边界说明，指出这些只是设计建议，需在你自己的工具中、并用色盲模拟器核实。

## 局限

- 这只是设计草稿，不是渲染好的图表。助手并未执行或渲染任何内容。
- 对比度说明仅供参考；你若未提供背景颜色，提示词会假设为白色并说明这一点。
- 助手看不到你的数据数值，无法打开你的制图工具，也无法替你应用这些颜色，且不得声称无障碍认证。
- 上述来源提示词中存在“四对五”的示例数量缺陷；这是原始文本的问题，与你的数据无关。

## 常见问题

**需要特殊软件、终端或 API 密钥吗？** 不需要。任何能接收文字的 AI 对话即可；提示词只产出一份文字草稿，供你复制到自己的设计工作中。

**如果系列清单为空，或两个系列名称重复怎么办？** 提示词会让助手主动索要清单，或请你区分重复项，而不是自行猜测；同时也不得悄悄新增、删除或合并任何系列。

**我粘贴的内容私密吗？** 提示词运行在你使用的那个对话账号中，处理方式取决于该服务商；如果账号设置不允许，请不要粘贴机密名称。

## 核实说明

## 完整可复制提示词

# 色盲安全图表配色起草器

你要帮助我为一个我自己要制作的图表选择颜色和冗余线索。我将在下面粘贴一份数据系列清单。只以该清单为依据。不要编造数据数值、分组归属、标签或额外系列。

## 我将提供的内容

我粘贴一份清单，每行一个数据系列，形式如下：

- 系列名称
- 可选：一句关于该系列代表什么或与其他系列关系的简短说明

我还可以选择粘贴我的图表背景信息（图表类型、背景颜色、用于打印还是在屏幕上显示，以及任何我必须保留的颜色）。

## 你的任务

1. 阅读我的系列清单，并确认你找到多少个不同的系列。如果有任何一行含义不明确，向我提出一个问题，而不是猜测。
2. 提出一套配色方案，其中任何两个系列都不能只靠色相差异区分。力求在明度上也有差异，而不仅在色相上，这样这套颜色对红绿色觉、蓝黄色觉或低色觉的人也能区分。
3. 为每个系列给出一个候选颜色的十六进制色值，外加一段通俗描述。若我必须保留某个现有颜色，请围绕它来安排。
4. 为每个系列添加一个不依赖颜色的冗余线索：线型、标记形状、直接文字标注、填充图案或图内简短标记。请明确给出该线索。
5. 说明每种颜色与我的背景之间的对比度。如果我没有指定背景，假设为白色并说明这一点。如果某颜色与背景或颜色与颜色之间对比度偏弱，请标注出来并提供替代方案。
6. 给出一份简短的备用方案：如果这些颜色对某位特定读者或某种输出仍然失效，什么文字标签、排序或注释能让每个系列在不依赖颜色的情况下被识别出来。

## 输出格式

按顺序返回以下各节：

- **系列数量与疑问**：系列数量，以及任何未决疑问。
- **颜色表格**：列为 `系列 | 十六进制色值 | 描述 | 冗余线索 | 对比度说明`。
- **成对警示清单**：你认为难以区分的系列组合，每对附一行修正方案。
- **纯文字标签备用方案**：为每个系列给出能在单色版本中识别它的最短标签或注释。
- **边界**：一行简短说明，指出这些只是设计建议，我必须在自己的工具中、并用色盲模拟器核实最终图表。

## 不确定性与缺失输入

如果我的系列清单为空，向我索要。如果两个系列名称相同，请先让我区分它们再继续。如果我没有给出背景颜色，请在对比度说明中写明假设为白色背景。不要悄悄新增、删除或合并任何系列。

## 完成前的审查检查

- 我清单中的每个系列是否都在表格中只出现一次？
- 每个系列是否都有一条能在黑白打印下存活的线索？
- 是否有任意两行的十六进制色值主要只在色相上不同，而明度近乎相等？如果有，修正那一对。
- 你是否避免了就图表在某个具体产品中会如何渲染做任何表述？

## 边界

这只是设计草稿，不是渲染好的图表。你看不到我的数据，无法打开我的制图工具，也无法替我应用这些颜色。不要声称无障碍认证。当某个判断不确定时，请明确告诉我。

## 输入形式的虚构小示例

- 广告触达人数
- 广告点击量，备注：总是低于触达人数
- 广告支出
- 广告转化量
- 背景：白色。图表：分组条形图。

## 示意性输出形态（非真实数值）

一张五行表格，每行包含一个十六进制色值和一段描述，例如“中深蓝”；一条冗余线索，例如“实心填充加末端直接标注”；以及一条说明，例如“与白色对比强；打印时保留”。然后是成对警示清单，点名“触达”对“点击量”以及“点击量”对“转化量”，每对附一个修正方案。接着是每个系列的简短纯文字标签备用方案，例如“触达”“点击量”“支出”“转化”。不要把这些形态当作最终内容：真正的行和警示应根据我提供的系列清单推导出来。

## 对照我的示例检查

对于上面的虚构清单，满足以下条件才算通过：五个系列全部出现；没有任何两个系列仅靠色相区分；每行都有一条可打印的线索；薄弱组合被点名并给出修正方案；单色读者仅凭标签仍能区分“触达”、“点击量”、“支出”、“转化”。如果有任何系列缺失、某个线索依赖颜色，或者某对难以区分的组合未被标注，则判为不通过。
