SuccessFactors Accessibility policy includes practices that help prevent people with disabilities from being excluded from accessing content. This includes designing for users with color vision impairment (also known as color blindness).

Problem Summary

We don't recommend using using color contrasts alone to communication information in data visualizations ("color coding") because it can cause problems for those with color vision deficiencies. They have difficulty perceiving certain color contrasts due to colors shifting. However, the use of color can enhance comprehension. There are also times when some amount of color coding can't be avoided; for example, in many charts and graphs.


By using a custom color-safe palette that has colors that won’t shift, we can be assured that information is communicated correctly to users with any of the three most common types of color vision impairment: Deuteranopia, Protanopia and Tritanopia.

However, having designers manually create versions of data visualizations that use these color-safe palettes would be time consuming and labor-intensive. Instead, we've created a tool that tells the system when to use a custom color palette. In addition to helping our content be more accessible, this solution saves time and effort for visual and UX designers.
