What is red box, yellow box and green box testing?

Question

I can find many explanations on difference between black box and white box testing, but couldn't find any better explanation on Red box, Yellow box and Green box testing.

Can someone please explain these types of testing terms? Examples will be appreciated.

Thanks in advance.
