Htc Evo 4g Font Colors

[Faye27]

I have an htc evo shift 4g cell phone. I somehow changed the font color from green to blue. I did this on accident, so I don't have no idea where to start at on my cell phone to change the color from blue to green. Does anyone know where I go to on the cell phone and how to change the font colors? Please help! Thank you! Faye27
