Posting of re-colored themes?

[themapleboy]

Hello, I am quite new to Rockbox but am enjoying myself quite thoroughly.  While looking to the selection of themes i was dissapointed with there not being a high contrast theme that looked good (in my opinion). I discovered the invert colors option in lcd settings and was quite pleased with that for a while. But began to dislike it inverting everything (gameboy, movies, album art etc.). So i re-colored the theme Ambiance B-mod  for the sanza-fuze. I feel that it is quite difference and would like to share it with the community. What are the rules for posting themes that are just modified versions of another? thank you

tl;dr: What are the rules for posting re-colored themes?



Here are some pics of what I have done.

the theme site requires a very flexible license for all themes, so IIRC as long as you attribute the original work you are fully entitled to upload with as few changes as you like
