You are correct, the 0.50 does tell you that part of the map will have this
color.

If it's really the 0..1 scale that you don't like, you can use anything as
an upper bound really and then divide the vector by that number. <124, 255,
40>/255

But if visualizing what color this will make is the problem, you could use
something like the GIMP (http://www.gimp.org/) which has a color picker that
displays the RGB componants. There are other standalone tools as well.
Someone in these groups has developed a tool called POVColor that might be
usefull: http://www.sourceforge.net/projects/povcolor
