The following colors can be used against white backgrounds and meet color contrast requirements. Many grays, yellows, oranges, and reds do not have sufficient contrast with a white background or text. The default Canvas color picker also provides many colors that don’t meet accessibility requirements. When in doubt, use the color contrast checker to determine if a color combination is accessible.
