Hey,
all dynamic colors are defined in the head section of your html document. You can view the source code to find the right elements/colors. You can change the primary color with following code in css/custom.css:
#top .on-primary-color, #top .on-primary-color a, .dropcap2, div .button, input[type="submit"], #submit, .info_text_header, .info_text_header a, .info_text_header a:hover, .contentSlideControlls a.activeItem, #top .related_posts .contentSlideControlls a.activeItem, .contentSlideControlls a:hover, #top .related_posts .contentSlideControlls a:hover, #top th, #top th a, a.button:hover, .callout a, #top .big_button:hover{
color:#ffffff !important;
}
You can change the color values or add/remove elements from the list.
