Blue = rgb(0,0,255): Light Blue = rgb(152,152,255): Dark Blue = rgb(0,0,152)
Yellow = rgb(255,255,0): Light Yellow = rgb(255,255,152): Dark Yellow = rgb(152,152,0)
Blue-Green = rgb(0,255,255): Light Blue-Green = rgb(152,255,255): Dark Blue-Green = rgb(0,152,152)
Violet = rgb(255,0,255): Light Violet = rgb(255,152,255): Dark Violet = rgb(152,0,152)
Orange = rgb(255,152,0): Light Orange = rgb(255,152,63): Dark Orange = rgb(152,63,0)
