Hi.
You have the “Set Featured Image” link in the “Featured Image” box on the post editing page, when you set the Featured Image using this link for it will appear on Home page.
Don’t quite understand your 2nd question. what colors you need to change?
And about the 3rd question – I see you have Woocommerce plugin installed and i think this article can help you – https://docs.woothemes.com/document/product-variations/

@andy,

I’m using image host, do you know how to set the featured image by url?
