how to change the color text on your envelope tf3d screen tab

[popasmurfn25]

ok, i have the transparent envelope on my mail tab of touch flow
theres a text feild at the bottom of envelope that tells you what
email account your on its black text,i was wondering if i can change this color
through regestry? Because the background image im using is black so the text
is blacked out,and if i change the wallpaper to white then i cant see my other
text on other tabs becase its white, why not red then i know....
