"What is this colour." shoukd be allowed in this test.

What is this color

What is this color should be accepted.

5 months later and still not accepting what is this color. I don't think anyone looks at our reports.

Which color is this?

I'm trying to figure out if there is a difference between "What is this color?" and "What color is this?" I think there is a distinction in English. For example "this color" can only refer to the color, whereas "is this" refers to an object. So it could be What color is this (car)? for example. But it seems pretty nit picky.

what is this colour is also correct

what colour is this is also correct

as above.Soooooo silly

WHAT IS THIS COLOR!? I lost my last health point and my answer was correct! -__-
