Modification of the pallets:
You can decide to color in red your image for example, or purple by putting red and blue... Attention, if you put the red at 50 for example and that you record, if you want to return to the colors of origin, you will not be able to do it by putting -50 (there is no way, with share while giving a safeguard of the files).
Attention with this function, because you can modify a pallet which is used by autes images, which is likely to modify all the play. To be sure that you modify a pallet without any risk, it is enough to look at the name of the pallet. If the name of the pallet resembles in the name of the image, that wants to say that it is a specific pallet and you can thus modify it as you want, Ca will modify just the image (or groups it image of the same name, like all the images of the same monster).
