You should be able to change the font color. Here's what you want to try. Make a system restore point before just in case.
Start> In the search box, type window color, and then click Change window colors and metrics.
In the Item list, click the part of Windows that you want to change the font for. For example, if you want to change the menu font, click Menu in the list.
Then, make any of the following changes:
In the Font list, click the font that you want to use.
In the Size list, click the font size that you want.
In the Color list, click the font color that you want.
Repeat these steps for each item that you want to make changes to, and then click OK.
