You can find some colors in
this thread at xda. Personally, I'd learn how to do things on your own
.
Step 1: download cfcgui (google cfcgui xda)
Step 2: find 66ca6b9c_manila, 66dc841d_manila, 66ee9c9e_manila, 5568acf6_manila, 6700b51f_manila, 6712cda0_manila, 6724e621_manila, and 6736fea2_manila from your \windows directory and copy them to your desktop.
Step 3: extract .png's from the aforementioned ********_manila files with cfcgui
Step 4: edit .png's to heart's desire
Step 5: add .png's back to manila file with cfcgui
Step 6: transfer modified files back to your device using cfcgui
Step 7: enjoy new custom clouds
