alrite this is what you do if you have a downloaded skin:
go to:
" Documents\Sports Interactive\Football Manager 2010\skins\"skin name"\settings "
there it should be a file called something with the skin name. example "skin settings".
right click on that and open with notepad.
thing is though, i don't think it changes the in-game widget one as well.
but you can try anyways.
in notepad you should find something like this:
<!-- profile attribute colours -->
<colour name="low condition" red="169" green="23" blue="23" />
<colour name="mid condition" red="139" green="139" blue="139" />
<colour name="high condition" red="255" green="255" blue="255" />
you can change colours there.
heres a chart of colours with numbers:

everything at "255" and its white. everything on "0" its black.
