Color Contrast

Q: Why use Color Contrast on TypingMind?

Because you install it once and use it with any model. Color Contrast is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

Q: How do I install Color Contrast in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/thedaviddias/Front-End-Checklist/tree/main/skills/color-contrast. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Q: Which AI models can use Color Contrast?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

Q: How many AI models can I use with Color Contrast?

As many as you like. As long as a model supports skills, you can use Color Contrast with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Q: Is the Color Contrast AI skill free?

Yes. It is published on GitHub by thedaviddias under the MIT license. You only pay your own AI provider for the tokens you use.

Q: What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

Q: How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.

Published by thedaviddias on GitHub. Read the source before you install it.

Installation

Install the Color Contrast AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/thedaviddias/Front-End-Checklist/tree/main/skills/color-contrast
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/thedaviddias/Front-End-Checklist.git /tmp/Front-End-Checklist
mkdir -p .claude/skills
cp -r /tmp/Front-End-Checklist/skills/color-contrast .claude/skills/color-contrast

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Color Contrast in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Color Contrast on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Color Contrast is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Meet minimum color contrast ratios

Approximately 1 in 12 men and 1 in 200 women have some form of color vision deficiency. Low contrast text is also difficult for users with low vision, aging eyesight, or those reading in bright sunlight. Insufficient contrast is one of the most common WCAG failures and directly prevents users from reading content they need.

Quick Reference

Normal text (< 18pt or < 14pt bold): minimum contrast ratio of 4.5:1 — WCAG 2.1 SC 1.4.3 Level AA
Large text (≥ 18pt / 24px, or ≥ 14pt bold / ~18.67px bold): minimum 3:1 contrast ratio
Non-text UI components (icons, focus indicators, input borders): minimum 3:1 against adjacent color — WCAG 2.1 SC 1.4.11 Level AA
WCAG 2.1 SC 1.4.6 (Level AAA) requires 7:1 for normal text and 4.5:1 for large text
Decorative text and logotypes are exempt from contrast requirements

Check

Evaluate the contrast ratio between text color and its background for all text on the page. Use the WCAG relative luminance formula: for normal text (< 18pt or < 14pt bold), the ratio must be ≥ 4.5:1; for large text (≥ 18pt or ≥ 14pt bold), the ratio must be ≥ 3:1. Also check non-text UI components (input borders, button outlines, icons) for ≥ 3:1 ratio against adjacent colors per WCAG 2.1 SC 1.4.11. Check all interactive states: default, hover, focus, active, and visited.

Fix

Darken the foreground color or lighten/darken the background color until the ratio meets the minimum. For normal text failing 4.5:1: increase text darkness or background lightness. For large text failing 3:1: apply same approach with a lower threshold. Use a contrast checker tool (WebAIM, browser DevTools accessibility panel) to verify the exact ratio. Do not use opacity to lighten text — compute the effective blended color and check that ratio instead.

Explain

WCAG 2.1 SC 1.4.3 (Contrast Minimum, Level AA) requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (≥ 18pt regular or ≥ 14pt bold). Contrast ratio is calculated from the relative luminance of the foreground and background colors using the formula (L1 + 0.05) / (L2 + 0.05), where L1 is the lighter and L2 is the darker color. A ratio of 1:1 means no contrast (same color); 21:1 is maximum (black on white). Users with low vision, cataracts, or color blindness rely on high contrast to distinguish text from its background.

Code Review

Review the rendered markup and interactive states that affect Meet minimum color contrast ratios. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.
