Color Blindness Simulator
Preview up to 10 images under four kinds of color blindness and pick a palette that works for everyone.
Last reviewed October 11, 2026
About 1 in 12 men and 1 in 200 women see colors differently. If your game uses color to carry meaning (red attacks, green heals), some players cannot read it without help. The Color Blindness Simulator shows your art the way they see it, and suggests color sets that stay apart for everyone.
What this page helps you do
- Upload images of cards, boards or tokens.
- Compare the original with four simulations side by side.
- Pick a color-blind friendly palette of PANTONE colors and copy it for your printer.
You'll start from Tools, under the Pre-production or Designing chip.
Open the tool
In the sidebar, open Tools, click Pre-production (or Designing), then click Color Blindness Simulator.
Helpful details
- Key areas: an Upload Images area, a row of tabs for each kind of color blindness, and an Inclusive Color Palettes card.
- What you can do: work on the simulator and the palette picker independently.
- Good to know: the tool is listed under both Pre-production and Designing.
Upload your images
Drop in or choose up to 10 images. Any common image type works (PNG and JPG are typical).
Helpful details
- Key areas: the uploader processes each image as it arrives; a Clear All button empties the list.
- What you can do: upload one card and one board together and compare them in the same view.
- Good to know: processing happens in your browser. Nothing is uploaded to a server, and the images disappear when you leave the page.
Compare the simulations
Click a tab to switch the kind of color blindness. Each tab shows every image twice: the Original and the simulated version.
Helpful details
- Key areas: the tabs are Protanopia (Red-Blind), Deuteranopia (Green-Blind), Tritanopia (Blue-Blind) and Achromatopsia (Monochromacy, no color at all).
- What you can do: check two things. Can you still tell the important elements apart? Is the contrast still clear, or did two colors turn into the same muddy tone?
- Good to know: deuteranopia and protanopia are by far the most common. If you can only fix one thing, fix those first.
Pick an inclusive palette
In the Inclusive Color Palettes card, click Choose Colors.
Helpful details
- Key areas: the Color Blind Friendly Palette dialog groups PANTONE swatches into Neutral (pick up to 4), Warmer, Soft, Deep and Bright (pick 1 from each). A Preview shows your selection, with a count of colors chosen.
- What you can do: click Copy Colors Info to copy the PANTONE names and hex codes, then paste them into your Component Spec Sheet or send them to your manufacturer.
- Good to know: the groups are built so that one color from each stays distinct under every simulation. Mixing two from the same group is where confusion starts.
Fix what fails
When two elements look alike in a simulation, add a second cue that does not depend on color.
Helpful details
- Key areas: an icon, a label, a shape or a pattern (stripes, dots, chevron borders).
- What you can do: swap one color for a different group in the palette picker, or raise the light/dark contrast, which works for everyone.
- Good to know: you do not need to redesign the game. You need color plus one more signal.
Tips & common questions
Can I download the simulated images? Not from the tool. Take a screenshot if you need to share a comparison.
Can I check a whole rulebook? Export the pages as images (up to 10 at a time) and upload them together.
Does the tool change my original files? No. It only reads them to draw the simulations.
Which simulation matters most? Deuteranopia and protanopia together cover almost all cases of color blindness. Start there.
