It other cases you are going to have to find the spell.m2 that you want to modify. Extract it and look at it with m2modder. It should be made up of both particles and .blps. You can edit the .blps with the .blp converter and photoshop. For the particles edit them through m2modder. If you go to change color you will see an 8 digit code. The first 2 digits are the transparency (leave these alone), the last 6 are a hex color code. You will have to play with it as the method is not perfected. Finally, I don't think there is a way to change the color of the tail although, I think that the tail color may be in another .blp. Hope that helped. Feel free to ask questions.
