those colors are set in the http://gfcreativeinc.com/clients/neograft/webassist/forms/fd_compact_default.css file
for example:
form.Compact_Default .textfieldFocusState input, form.Compact_Default input.textfieldFocusState {
background-color: #FFC;
}
i suggest using Fire Bug in fire fox to inspect the elements on the p[age and locate the CSS that effects them.
