+ | When changing the color of the text on the OVERLAY using the same rgn_idx=1 the last command issued will override both channels, the text will still be different but the color will be the same because they are using the same shared rgn_idx | ||

+ | PNG will work in the same way but you would only want to do this for 2 of the same PNG\\ | ||
+ | Using different PNGs would cause colors to go wonky (CLUT is now different at the rgn_idx) | ||
+ | |||
