I recently saw some minis painted with Green Stuff World’s “Chameleon Paint” and really liked the effect. Got some of those paints and played around with them a bit. While the color shift properties of the paints are not as strong as I would have liked, the effect is rather cool nonetheless.
The first model I used the paints on is a Lera (or Mothfolk) from Ghamak’s Patreon. Applied three different chameleon paints on the wings to get a nice color transition.
