Color preview not working properly. #2606

What I should be getting:

Clearly the issue is because whatever code you guys are using to generate color in that square box is not checking if the Color object is there in comment. It is simply finding all Color objects as if in plaintext and mapping them to line numbers; the color which is found last in a line is retained as the key and rest are discarded.
