Hi all. My hl PzIV came with a hole in the side, I assume was for the old "A,B,C" switch. I glued a white piece of styrene over it and brushed on some Tamiya XF-60 Dark Yellow. When it dried, it took on a greenish tinge which doesnt match the rest of the tank. Maybe if I mix a bit of white in it will it match? Sorry, I havent had much experience with these colors.
