Does Google ignore forwarded domains?

[coffeemaker]

I have setup a few new domains which forward (with masking) to subdomain on my main site, but seems like Google ignores them.

I started them over a month ago, submitted them to Google, and they are still not included.

For example:
www.site3.com forwards to site3.site2.com which forwards to www.site1.com

How can I get Google to include www.site3.com? Or does Google just ignore forwarded domains?

Do you mean that site3.com just redirects to site1.com? If that's the case, then why would google want to include an empty domain in their index? They'd just include site1.com because that's where the content is.

Content is the same except for the branding at header and footer, and also colours look different.

It is all designed to look like a different website, but use the same content.

I suppose Google doesn't like this

I'd suggest you remove the duplicates otherwise all your sites will face the sandbox from google, they do not like this one bit! That includes your main one and there isn't any coming back from that!

you need to do a 301 redirect instead.
