How do I change the font color in the username field?

[fxdigi-cash]

simply, if you don't know the color html code you want to change, then use Chrome browser and open your site and add a plug-in called color picker. After you installed it on Chrome, use that tool to identify what color you want to change. you will get the code, then look for it in your admin cp by searching in search style template option.

I think it shouldn't take more than 2 minutes to do all these steps.
