(Unrelated, but IDLgrColorbar__define has two underscores in and IDL
*will* be particular about it if you accidently name a class definition
routine with only one.)

I think you want:
oColorbar = OBJ_NEW("IDLgrColorbar", R_CURR, G_CURR, B_CURR,
SHOW_AXIS=1, Title='values', HIDE=0)
i.e. color table values as three separate parameters instead of one long
3 * 256 element array.
