Color blindness checker

As explained in Everyday Data Visualization

A color blindness checker is a software feature that simulates how a visual design appears under different color-vision deficiencies.

A color blindness checker simulates how a visual design appears under common color-vision deficiencies, helping test whether its palette remains distinguishable. section 8.4.3

Use the checker as a quick palette review:

  • Generate or refine colors in Coolors, then run its built-in color blindness checker on the final palette. section 8.4.3
  • Check simulations of the most prevalent color-vision deficiencies before assigning colors to important dashboard metrics. section 8.4.3
  • Keep each color’s meaning consistent throughout the interface so users can remember what it represents. section 8.4.3

Hospitality dashboard palette

A hospitality dashboard used two logo colors for its most important metrics, tested the complete palette with Coolors, and accepted the simulations because no explicit accessibility needs were specified. section 8.4.3

How Everyday Data Visualization covers it

How deep it goes
Demonstrates a practical palette check and its project-specific sufficiency, without detailing simulation algorithms or accessibility standards.
Examples
Uses a hospitality dashboard palette built from logo colors and tested in Coolors.
What you can do after
Evaluate a final color palette with Coolors and judge whether its simulated appearances remain acceptable.
How it connects
Connects color palettes, accessibility, color vision deficiencies, dashboards, and visual encoding.
