I think it would be better instead of:
color light-blue/black light-cyan/blue
something like:
#color normal [highlight]
#The format of a color is `FOREGROUND/BACKGROUND'
#Color name must be one of those:
#black, blue, green, cyan, red, magenta, brown, light-gray
#or those, but only for the foreground:
#dark-gray, light-blue, light-green, light-cyan, light-red, light-magenta, yellow, white
color light-blue/black light-cyan/blue
What do you think?
