I have a little something something for you today. After I uploaded my Bad Witch Overlay Default, I was asked if I could so a good witch default as well.
After figuring out what I wanted to do I set out to make it. Then it turned out that the 2 overlays are set up different so I had to throw my plan out the window.
So this is what I came up with after a few hours of trial and error. This default will add a little blue (to match the good witch theme) onto your sims cheeks, nose, and lips to give them the appearance of glowing slightly. I've tested it on multiple skin tones and it seems to look ok with all. It will not add any color to the body at all.
I used 2 different makeups by ZombieJill to make this. I altered the opacity and color slightly but all credit goes to them. (I used these and these)
