Summary description: Select colors with proper WCAG color contrast
Announcement text:
----------------------------------------------------------------------
The ninecolors package carefully selects and defines 9 colors
for 13 hues each. All colors with the same suffix number have
equal luminance level.
Also color black is of level 0, and color white is of level 10.
By simply choosing two colors in the above list, which differ
in level by at least 5, as foreground and background colors,
you will get proper WCAG Color Contrast.
