hello.
summary:
I have been handling what is the creation of sprites and I really already learned how to make them and make them work, however my problem is when applying transparency to multiple images.

in detail:
The project that I am carrying out is the creation of emoticons or reactions within the game, it is a simple complement so that they can be seen by everyone and "react" within the game.

I use "HLTextureTools" to make them, this program has the function of eliminating one of the colors you select to make them transparent within the game, all by your own choice, that is, you can choose the color you want to be invisible, but at the same time When you select that color, only the color you select from the first image is removed, the rest change colors and look ugly and different, as if all the colors had been interchanged from place.

I'm sure it may be an error when indexing the colors in PhotoShop, but I've tried several times to find the error and I can't, would someone have an answer about this?
Thank you very much in advance.
