In the documentation page for Picture.ColorizeMBS page, there’s this mention:
“Hue, Sat and Light in range 0.0 to 1.0 please.”
After spending a lot of time figuring out why it didn’t worked, I looked at the example and found this line:
lightness = light*2 - 1 //convert from 0-1 range to -1…1 range
So it looks like Light should be from -1 to 1, not 0 to 1.
If this is right, it’d be great to correct this.
