(LIGHT) - Lys/mørk smilies
Make any yellow smiley white, gray or black. To make a smiley lighter add several plus signs at the very end of a smiley, e.g #+++, to make smilies darker, add several minus signs e.g #----. If you have multiple color powers, you can create custom coloured smilies.
NOTE: Only works with smilies in brackets.
