One page checkout typeface colour

[hippooflove]

Hi

not sure if this in right section. it could fit in to a few.

I have just installed one page checkout from the prestashop addons. I have installed it okay (I think)

however in my shop the words for this checkout are in black and so is my background.

Any body tell me where and how I change the words to white in this module.

thank you

hippooflove.

ps if you know who the creator of the module is that may help me.
