just use SweetFX for colour fix the textures are good as is but you can make it so much more cinematic with SweetFX really makes things pop, I posted a thread up in this section about modded ME1+2 though the texture mod makes a huge difference combined with SweetFX it's amazing
Best thing about ME1 + 2 is it's lightweight so even with texture mods I can do sparse grid anti-aliasing for zero jaggies
