How do you edit jerseys on XBOX360?

I know this will sound stupid to most of you, but any help would be really appreciated.

When I try to create new jerseys using RED MC for Xbox360, i.e. the 14-15 pride jerseys, or the alternate New Orleans jerseys, I encounter a lot of problems:
1) when you enable custom jerseys colors, the team logo appears on the front of the jersey, and there seems to be no way to make it disappear.
2) finding the correct combination of colors is really hard, because the tutorial that comes included with RED MC seems to be wrong on that, but with many tries, you can get to the correct combination
3) editing an existing jersey texture to create a new jersey (for example the Pelicans Away for the red alternate) makes it so that the "base" color (in this case the navy blue) stays there and you can't edit it, so you will always have the red on top of the blue, resulting in a purple-ish jersey.

I know that the default answer to my doubts is that you can't edit much on consoles because you don't have the same access to files like for PC, but I'm pretty sure I've seen great stuff on some Xbox projects!

If I wasn't clear enough I could include some pictures I guess, but does anyone know how to solve those problems?
