Screenshots of what you're doing.

Yes, I will have to work on the colors - they are, in the materials, original color codes of the official logo, but what blender does to them makes them look slightly different. For example the greenish glow around the ring is actually bright blue, but the blur shaders seem to transform the color too much. As for the orange and yellow, that's how sparkles behave... I'm not sure if I can actually change this? I can hardly make the sparkles use Xonotic color scheme and still look like sparkles... I'll see what I can do. Thanks for the feedback though, I've looked at this so much that I've grown used to these colors already :oD
