Make more colors for light spells and make the current ones better (ie. teal, pink, brown, black, ect). Make the current colors better
purple (darker and more purple) and blue(looks white, need darker and more blue), white(looks more yellow, set current blue color to white))
Green and red - in a good spot and tell what colors they are
Orange and yellow, can tell, but could be better bit hard to know exactly what the color is
This would allow the need to be changed for any item that gives colors.
I do understand that colors will look different for each user depending on screen settings, when testing this with others, they could not guess the colors I had used on different NPC for some of the colors and it does not look anything like what they should be.
