+		This package carefully selects and defines 9 colors for 13 hues each.
+		All colors with the same suffix number have equal luminance level. Also
+		the color black is of level 0, and the 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.
