]admin cp -> Styles -> Modify -> choose one -> [fonts/colors/etc]

now for textarea (replybox etc) change this :

TEXTAREA, .bginput {
	FONT-SIZE: 12px;
	FONT-FAMILY: Verdana,Arial,Helvetica,sans-serif;
	COLOR: #000000;
	BACKGROUND-COLOR: #CBC9C9
}

to

[TEXTAREA, .bginput {
	FONT-SIZE: 12px;
	FONT-FAMILY: Verdana,Arial,Helvetica,sans-serif;
	COLOR: #000000;
	BACKGROUND-COLOR: #000000
}

It should help... Also take a look at the same page under "Main Colors".
By the way, I can't see that u are using anby of mine templates... I haven't registered, that's maybe why...
