If you translate HSB into HLS (Hue, Lightness, Saturation) or HSB
(Hue, Saturation, Brightness) you can use the IDL procedure
COLOR_CONVERT to convert to and from RGB.

Is the conversion 1 to 1?

That depends upon the implementation and the color coordinate system
used: RGB is a cube, HSB is a cone and HLS is a double cone (if I
don't intermix HSB and HLS).
