Color blindness affects 3 million people globally, so this is a visual impairment that matters more than one would think. What could be the problem with color blindness in Salesforce?

With Salesforce we all love Dashboards for information at a glance. Charts and graphs work well, and they look good. The issue with the default palette (and majority of the palettes) in Lightning dashboards is the lack of contrast between colors. Since there can be/are color blind people using Salesforce, it would be great to know how to accommodate these users.

I found this article on how to change the colors of a dashboard with themes and palettes (Only available in Salesforce Lightning Experience):

In the article it specifically mentions the "Mineral" palette for High Contrast. While for most users this palette wouldn't look the most attractive, visually, it does serve a very useful purpose. Those that are color blind need very different colors to see color changes. The "Mineral" palette works because it alternates completely different colors on the color wheel. The color blind user might not be able to tell exactly which color they see, but they will see a difference in colors, making the graphs and charts readable.

One color example, if you have a blue and purple together they are going to look about the same to a red/green color blind individual because they can't see red mixed with blue, in the color purple. It would just look like blue next to blue.

There is a variety of colors that can be affected with color blindness and many causes from birth to later in life. Unfortunately this palette change only helps with graphs and charts, but it’s definitely something worth looking into for those that need it.

**Salesforce Classic and Color Blindness- There is a checkbox in the User Record for a Permission, called “High Contrast Palette on Charts”. I am sure that it once worked, however, with me playing around with it and researching what I could online, I do not see a difference with the box checked or unchecked. If you are able to get it to work I would love to know the secret.
