Subject: [PATCH] Update color.lua

Inside 'rgbToHsl', the variable 's' was mistakenly re-declared as local inside the if/then/else block.
This caused the function to return saturation either as '0' (for b/w rgb values) or as 'nil' (for all the other cases).

The statement (line 26) was commented, but it can be permanently removed.
