Accessible Infographics Colors?

Hi All,

I some questions about infographics (pie charts, bar charts, etc) and
color accessibility. Are there any guidelines or articles that you know
of on how to make the colors in these cases accessible?

What are the specific instances when the colors need to be accessible in
a chart? For example, in a pie chart, do the colors need to be
accessible against each other so that each slice's color contrasts
properly against the color of the neighboring slice? Or would it be
sufficient to just have a white (or other contrasting color) border
between each slice?

Textures and patterns are certainly an option. But, for now, I'm more
concerned about colors and contrast.

TIA!
