Button text colors

And there I go, asking for help again...

I'm having some issues to deal with my board default button colors, since everytime I change the codes for those, the input fields get colorred too and everything turns nasty. Right now I'm having this problem:



As you can see, the normal button text color is white. When I change the css for that, my input text changes aswell and everything gets nasty... I think I'm changing more css than I was supposed to, so if anyone could let me know the specific line for the buttons, it would be appreciated!

ps. I was using the codes found here to change the default button colors, but those change my input colors too and I dunno what to do...
