Most 2d paint programs work with integer values for the colour
components, which range from 0 to 255. To convert values like that to
POV floating point components, divide by 256.

So if you find a colour you like in your favourite 2d paint program and
make a note of the RGB values. Then write something like

        rgb <23,46,230>/256 

To interpret "rgb <0.1, 0.2, 1>*0.9" perform the specified
multiplication and then further multiply by 256 and round to an integer

"rgb <0.1, 0.2, 1>*0.9" = "rgb <0.09, 0.18, 0.9>" = RGB[23,46,230]
