Changing color of TNT / Nitro

[wookiewolf342]

Hi all - I figured out how to switch the wooden texture on most crates by replacing the ColorMap,textures@!levels!Crash1!crates!C1_WoodCrate_c`tga,111 texture with my own image. 

Just curious - would anybody know how I would go about switching the color of Nitro or TNT crates?

Thanks a ton
