[kubuntu] Is there any way of getting around dark color schemes?

view story

http://ubuntuforums.org – I like dark colors for my desktop customization, dark greys, ect. Only problem is it affects more than I'd like. Such as internet sites, buttons being black with black text, or text boxes black and the text isn't white it's black :/ it's rather frustrating. But I was wondering if any of you have gotten around it? (Hardware)
