What is the Color-Blind-Safe Palette Generator?
Picking colors that look distinct to you is not the same as picking colors that stay distinct for the roughly 1 in 12 men and 1 in 200 women with a color vision deficiency. This tool generates a palette by sampling many candidate hues, running each candidate through real color-vision-deficiency simulation matrices for protanopia, deuteranopia and tritanopia (the three common types), and keeping only the set whose pairwise color difference stays high across all three simulated views, not just normal vision.
This is the opposite job of a colorblind simulator, which shows you how one image looks to colorblind viewers — this tool instead generates new colors from scratch that are verified in advance to survive that simulation, so you can use them directly in a chart, a map legend or a UI without needing to test them afterward.
3 steps to your result
Open the tool and follow along. Nothing to install.
What you get
Each candidate color is transformed through real protanopia, deuteranopia and tritanopia simulation matrices, not a rule of thumb.
Colors are only kept if they stay perceptually distinct from every other color in the palette under all three simulated conditions.
Generate anywhere from 3 up to 12 distinct colors for charts, categories or map legends.
Every generated color is shown with its HEX and RGB value, ready to paste into your design tool or CSS.

Questions people ask
How is this different from a colorblind simulator?
A simulator (like this site's Color Blindness Simulator) shows you how an existing image looks to colorblind viewers. This tool does the opposite — it generates brand-new colors from scratch that are already verified to stay distinct under that same simulation, so you don't have to test and redesign afterward.
What color vision types does it check?
Protanopia and deuteranopia (the two red-green types, together affecting the large majority of colorblind people) and tritanopia (the rarer blue-yellow type) — a palette is only returned if it stays distinct across all three.
How many colors can I generate?
Between 3 and 12 — fewer colors can be spaced further apart and stay more reliably distinct; if 12 colors look too close together, try a smaller count.
Is this palette also fine for people with normal color vision?
Yes — colors verified to stay distinct under color-vision-deficiency simulation are, in practice, also clearly distinct for typical vision.
Can I use these colors commercially?
Yes, the generated HEX/RGB values are just numbers — use them freely in any project.
