Five concrete examples of the Color Blindness Simulator in real use. Each one shows the situation, what you put in and what comes out, so you can copy the structure, swap in your details and adapt it this week.
Example 1: Checking a chart where colours carry meaning
The task: Checking a chart where colours carry meaning. You start from colours or an image plus the deficiency type you want to simulate.. The tool returns the same content shown as a person with that deficiency would see it., giving you proof of whether your colour-coded information survives for the millions of viewers it would otherwise exclude. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 2: Verifying a status palette still separates states
The task: Verifying a status palette still separates states. You start from colours or an image plus the deficiency type you want to simulate.. The tool returns the same content shown as a person with that deficiency would see it., giving you proof of whether your colour-coded information survives for the millions of viewers it would otherwise exclude. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 3: Testing brand colours for collisions
The task: Testing brand colours for collisions. You start from colours or an image plus the deficiency type you want to simulate.. The tool returns the same content shown as a person with that deficiency would see it., giving you proof of whether your colour-coded information survives for the millions of viewers it would otherwise exclude. you can edit rather than a blank page.

Example 4: Auditing an infographic before publishing
The task: Auditing an infographic before publishing. You start from colours or an image plus the deficiency type you want to simulate.. The tool returns the same content shown as a person with that deficiency would see it., giving you proof of whether your colour-coded information survives for the millions of viewers it would otherwise exclude. you can edit rather than a blank page.

Example 5: Preparing accessibility documentation
The task: Preparing accessibility documentation. You start from colours or an image plus the deficiency type you want to simulate.. The tool returns the same content shown as a person with that deficiency would see it., giving you proof of whether your colour-coded information survives for the millions of viewers it would otherwise exclude. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
A Full Worked Example
Input: palette #22c55e (success) and #ef4444 (error) · deuteranopia
Both colours converge toward similar olive tones - a warning that red-green pairing fails.
The pattern behind every example above: context and constraints go in, structure comes out, and your edit makes it true.
How to Build Your Own Examples
- Take a task already on your calendar for this week.
- Write the brief in two sentences: the job and the audience.
- Generate, compare against the version you would have written manually.
- Save the prompt alongside the result so the second run takes seconds.
Getting More From Each Example
Most people stop at the first result. Generate a second version with one changed variable - length, tone or angle - and compare. The better version usually appears on the second run, not the first.
Frequently Asked Questions
What types of colour blindness exist?
Red-green forms are most common (deuteranopia and protanopia); blue-yellow (tritanopia) is rarer.
Does passing the simulator make my design accessible?
It is one essential check - combine it with contrast ratios and non-colour cues.
Can I simulate an image or only colours?
Both - test individual swatches or preview a whole graphic.
Is anything uploaded?
No - simulation runs entirely in your browser.
