RGBF
c = RGBF (r, g, b)
Returns the RGB color code for the specified color values.
r, g and b are the three color
channels red, green and blue and take floating point values from 0 to 1
for each of the colors. Values outside that range will be clamped. The
return value is a negative 24bit value to be used by the drawing
functions.
