modding 7

First make a backup of the aero.msstyles file!!!
What U need is :
1. Restorator - for extracting/importing files in to aero.msstyles
2. Some graphical software - that can edit png files.
3. XVI32 - Hex editor for variant/normal color

1,2 are needed and 3 is optional because most of the colors are in png pictures.

When U have all that is needed
then copy aero.msstyles to some place easy for work/find
-start restorator
-open aero.msstyles (look the left side)
-find IMAGE and select it
-all basic and aero are in 508.png - 1108.png (picture 971.png is under STREAM)
In the earlier posts U can find the picture numbers for the start menu.
U need to edit only the white color on the pictures if U wish to replace only that.
Or U can download this pdf with some info what number is what picture (7600 Windows 7 x64)
