Diverging Colors for Color Vision Deficiency

Eric McDonald Oct 15, 2013 8:54 AM

I'm using a red-green diverging palette to show positive and negative positions on a chart / table. I need to use a palette which is suitable for someone with red-green color vision deficiency (color blindness as it's often called). Tableau has a Color blind palette but not a diverging one. What colors should use to replace red-green diverging and which work correctly from a visual design perspective?

We have our own corporate palettes which we use in tableau so we can add our own but need to know best practice.

My recommendation is to replace red-green deverging palette by red-white-blue or red-yellow-blue diverging palette.

You can see other diverging palettes in ColorBrewer tool by Cynthia Brewer

See the screenshot:

Recently Jewel, from Tableau Public, published a blog post Choosing Color for Accessibility including other types of palettes and she shared the preferences.tps file.

I hope this help.

The orange>blue diverging seems popular

Take a look also to this thread How to use Color Brewer based Custom Palettes in Tableau
where Michael Christini shared the preferences tps file with the color brewer specifications.
