What it does
Colour Independence is an agent skill from Owl-Listener/inclusive-design-skills. Design interfaces where colour is never the only way information is communicated. Use when designing status indicators, data visualisations, form validation, alerts, maps, or any content that uses colour to convey meaning. Triggers on: colour blind, color blind, colour alone, color alone, colour vision, color vision, red green, deuteranopia, protanopia, tritanopia, colour coding, status colour, chart colours, accessible colours.
Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design, covering Data visualization and Forms and validation. The repository describes itself as: Inclusive design skills for AI coding agents — from cognitive accessibility to adaptive interfaces, inclusive research, and accessibility decision-making. The licence is MIT.
When your agent uses it
- Designing status indicators
- Data visualisations
- Form validation
- Any content that uses colour to convey meaning
Example prompts
- “/colour-independence”
What it can do on your machine
Read from SKILL.md and the folder at commit 6e0740f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Colour Independence loads about 868 tokens when it runs. Until then it costs about 113 tokens; SKILL.md has 427 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- colour-independence
- description
- Design interfaces where colour is never the only way information is communicated. Use when designing status indicators, data visualisations, form validation, alerts, maps, or any content that uses colour to convey meaning. Triggers on: colour blind, color blind, colour alone, color alone, colour vision, color vision, red green, deuteranopia, protanopia, tritanopia, colour coding, status colour, chart colours, accessible colours.
Colour Independence
Design so that every piece of information conveyed by colour is also conveyed by something else — shape, text, pattern, position, or icon. 8% of men and 0.5% of women have colour vision deficiency. That's roughly 1 in 12 of your male users.
Core Principle
Colour can enhance meaning. Colour must never be the only carrier of meaning.
Common Failures
Status Indicators
- Bad: green dot = online, red dot = offline (colour only)
- Good: green dot + "Online" label, red dot + "Offline" label
- Better: green dot with tick + "Online", grey dot with x + "Offline"
Form Validation
- Bad: red border on invalid fields (colour only)
- Good: red border + error icon + error text message
- The error message does the real work — the colour is reinforcement
Data Visualisation
- Bad: line chart with 5 coloured lines, legend uses colour swatches
- Good: different line styles (solid, dashed, dotted) + labels + distinct colours that work in greyscale
- Good: bar chart with patterns (stripes, dots, solid) alongside colour
- Always test charts in greyscale — can you still read them?
Links
- Bad: links distinguished from body text only by colour
- Good: links are coloured AND underlined
- The underline is the accessible indicator — colour is the enhancement
Alerts and Badges
- Bad: red badge = urgent, yellow = warning, green = ok
- Good: red badge + "Urgent" label, yellow + "Warning" label, green + "OK" label
- Icons reinforce: ⚠ for warning, ✓ for success, ✕ for error
Maps and Diagrams
- Bad: regions coloured to show data (choropleth with no labels)
- Good: colours + patterns + values displayed on each region
- Good: interactive with values on hover/focus AND a data table alternative

Design Patterns
Double Encoding
Every colour meaning gets a second encoding:
- Colour + icon
- Colour + text label
- Colour + pattern or texture
- Colour + shape
- Colour + position
Accessible Colour Palettes
- Choose colours that are distinguishable in all types of colour vision deficiency (not just red-green)
- Use a colour blindness simulator to test your palette
- Blue and orange are generally safe for most types
- Avoid red/green as the only pair distinguishing two states
- Ensure sufficient contrast between adjacent colours in charts
Greyscale Test
Quick check: convert your interface to greyscale.
- Can you still use it?
- Can you distinguish all status states?
- Can you read the chart?
- Can you tell which fields have errors?
If any answer is no, colour is carrying meaning alone.
Assessment Checklist
- No information is conveyed by colour alone
- Status indicators use colour + icon + text
- Form errors use colour + icon + message
- Charts are readable in greyscale
- Links are distinguishable by more than colour
- Alert levels use colour + label + icon
- Data visualisations have patterns or labels alongside colour
- Interface passes the greyscale test
