The region index value is system-wide and can be in the range of 1 to 16.

 + 
 +In the above example, identical region indices are used, effectively reusing the CLUT. The text will be correct on each channel. When changing the color of the text, when using identical region indices, the last Overlay command issued will override all Overlay instances that are using the same region index, the text will still be different but the color will be the same because they are using the same shared rgn_idx.

 +PNG overlay will work in the same way as text overlay when re-using region indices, but this is only helpful when overlaying identical PNGs.\\ 
 +Using different PNGs would cause colors to go wonky due to differing CLUTs for the different PNGs.
