Well I try to respond to my themes as soon possible.
I recommend getting FireFox and Web Developer addon. This tool will allow you to see what style and underlying code you need to change to change the colors yourself. It's quite easy for you change it yourself, give it a go

Oh and please don't compare my crappy themes with Bloc's, he's are truly great creations where as mine are just rips and slight changes to the CORE theme (which I'm sure Bloc had a major design presence).
But thank you for your kind words, I'm humbled.
So give the changes a try, it is very simple and I'm sure you'll be able to do it. I'll try to guide you. You can even try the Online Manual for tips and pointers.
