Making a white colored rune

Does anyone know how I would go about making a white colored rune (I'm referring the the powerup runes, like Rune of Speed, etc.) I can get the other colors I want with tints, but white is impossible.

What program are you using?

I tried using Wc3 Image Extractor to find the skin for runes, but wasn't succesful.

import the following 2 .blps under the path textures\ it will make the rune glow white (like pic) and then you can tint it any color you want.

Thanks! One follow up question: how do I make this work with team colors? I tried adding an alpha channel to the .tga files, but for some reason that didn't work (the rune has the same color for all players).

the rune dosnt have alpha channels enabled, you cant team colorise it
