I have tried a few colour variations on the design template, from bamboo green to different image backgrounds. Its fun to explore the options and try a few combinations. I'm getting to be quite the blog expert ... I've already deleted this blog when I had practically completed all the exercises.  I hit the wrong exit button and it was tooo late, it was gone. So here  again, and many practices later, I've also got a blog for Promotion Literature with 20 book annotations.
So colour design, is great.
