I personally like the site.
Is the poison-green color chosen because of the name of the site (poison arrow darts)? I suppose everyone is saying go for red-white-black because that is what people expect from darts (in other words: thinking inside the box). You seem to be going for bold. Thinking outside the box isn't always the easiest to pull off. Good luck with the site.
I'd just keep adding products. If you have a million products to offer, people will get used to the color.
