Manage Color Contrast

Q: Why use Manage Color Contrast on TypingMind?

Because you install it once and use it with any model. Manage 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 Manage Color Contrast in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/gnurio/refactoring-ui-plugin/tree/main/skills/09-manage-color-contrast. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Q: Which AI models can use Manage 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 Manage Color Contrast?

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

Q: Is the Manage Color Contrast AI skill free?

It is published on GitHub by gnurio. Check the repository for licensing terms. 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.

Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by gnurio on GitHub. Read the source before you install it.

Installation

Install the Manage 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/gnurio/refactoring-ui-plugin/tree/main/skills/09-manage-color-contrast
Enable the skill in any chat where you want it available.

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/gnurio/refactoring-ui-plugin.git /tmp/refactoring-ui-plugin
mkdir -p .claude/skills
cp -r /tmp/refactoring-ui-plugin/skills/09-manage-color-contrast .claude/skills/manage-color-contrast

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

Use it in TypingMind

Enable Manage 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 Manage 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 Manage 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.

Skill: Manage Color Contrast

Purpose

Ensure text and interactive elements have sufficient contrast against their backgrounds for readability and accessibility.

Type

Evaluative + Corrective

Input

Text colors and sizes
Background colors
UI element specifications

Output

Contrast ratio calculations
Pass/Fail against WCAG standards
Recommendations for fixes

Transformation Performed

Calculates contrast ratios and ensures compliance with WCAG AA standards (4.5:1 for normal text, 3:1 for large text and UI components).

Decision Criteria

PASS (Good Contrast)

Normal text (< 18px): 4.5:1 minimum (WCAG AA)
Large text (≥ 18px bold or ≥ 24px): 3:1 minimum
UI components (buttons, inputs): 3:1 minimum for boundaries
Focus indicators: 3:1 minimum against adjacent colors

FAIL (Poor Contrast)

Light gray text on white (< 4.5:1)
White text on light colors
Disabled states that look like active (too much contrast)
Placeholder text same as input text

Contrast Ratio Quick Reference

Text Color on White	Ratio	Pass AA?
#000000 (black)	21:1	✓
#333333	12.6:1	✓
#666666	5.9:1	✓
#757575	4.6:1	✓ (minimum)
#999999	2.8:1	✗
#CCCCCC	1.6:1	✗

Common Failure Modes

Failure	Description	Fix
Light Gray Text	#999 or lighter for body text	Use #666 minimum, #333 preferred
Ghost Text	Placeholder same as value	Make placeholder lighter (#999)
Low-contrast Primary	Brand color too light for white text	Darken brand color or use dark text
Subtle Links	Links barely different from text	Add underline or increase contrast
Disabled Confusion	Disabled buttons too prominent	Reduce to 30% opacity or use gray
Icon Fade	Icons too light to see	Match text color or use higher contrast

Prerequisites

Color palette defined
Typography scale defined

Dependencies

Example Assessment

Input: Body text #888888 on white background

Evaluation: FAIL

Ratio: ~3.5:1
Below 4.5:1 requirement

Recommendation: Change to #666666 (5.9:1) minimum Prefer #333333 or #1A1A1A for body text
