Hi,
the problem arises partly out of the fact, that your color scheme is a bit illogical and “mixed”.
I like the general scheme of two tones of burnt siena with reddish ochre and black/dark brown (in the graphics).
This scheme works well and meshes well.
Your links and highlights however follow a totally different color scheme, which is not really linked – colorwise – with the other. It’s a “competitor” within the field of reds/redbrowns.
I’d either go for an antagonist color (like such pairs as red-green, blue-yellow, etc.), or I’d go for the same scheme as the main one, if you want a generally blended, calm look.
A good antagonist for your base scheme would be the leaf and olive greens. What also would work are either the turquoise blue shades or the cobalt blue shades.
The search button I’d give a toned down shade of whatever links colors scheme you decide upon. The textfields background I’d only slightly color, with a very light version of the text color of your body text (your main scheme), just so the extreme white is broken.
Regarding the links color scheme: the white for hover doesn’t work at all, that’s where you break colors a second time, the first break is – as I said – the clashing, competing clear orange.
I would have liked to make some concrete suggestions, but to be honest, your jumbled CSS file and finding the relevant spots there, was way too much trouble for this early hour. A tip: try to keep CSS nicely structured if you want people having a look and maybe helping. If they have to hunt through reams of non-structured jumbled text to pinpoint some specific class or tag, that’s asking a bit much ;-).
