crochet Dashiki Top Project

I'm excited about starting the Dashiki crochet project. I've been looking at this pattern for some time now. I found it in "Get Your Crochet On, Fly Tops & Funky Flavas" by Afya Ibomu (pg 48).

I went to the store this past Friday (Dot's) and found these hot lime-green earrings. This gave me a kick start inspiration to create the dashiki top in brown, yellow and green to match the earrings. I also picked up a necklace and bangle to go with earrings as a set.

Now, I'm a little discouraged as I try to find the exact color yellow and green I want for my top.
