Hello! Do we have color palettes for users who are color-blind?
Do we have a way to select a background color within the user's selected color palette which would:
I suspect that we may have One Network color palettes that have already been created with inclusionary principles for color-blindness. Is that so? If not, does anyone have suggestions for creating one within our system?
You have identified it correctly that using any specific color or set of color may or may not work for the colorblind person. The reason is that the type of colorblindness can vary from person to person.
Thankfully, you don't have to provide any special handling for colorblind people. When it comes to adding support for disabled people, ONE application complies with Section 508 and WCAG AA guidelines. WCAG AA level guidelines has provided a minimum required contrast ratio of 4.5:1 between colors of text and background. In ONE, screens like reports and TLV have a ratio of 12.63:1, which is higher than not just WCAG AA standards but WCAG AAA standards too. We have ensured that all the sections of the screen are compliant with this guideline.
In short, even though the application lacks the ability to select a secondary theme, colorblind users are not required to make any special changes because they can comfortably read all of the texts within ONE application in default theme itself.
