Published in the early 1960s, this story appeared in 'Tales to Astonish' or 'Journey Into Mystery', one of the Marvel titles that featured a superhero at the front of the book and a short story or two in the back. The plot: green-skinned aliens plan to invade the Earth, which they know about through some kind of super-television. They decide to send an advance scout, disguised as a human, to scope things out. During the transformation an alien doctor says 'Earthlings have only two eyes,' or something like that, and another says 'Pathetic!' They send their scout to Earth and he is immediately apprehended. The aliens are stunned, how did the Earthling know? The answer: their TV transmitted a black and white picture: they had no idea of human skin colors. Their scout was green.
3I’m not sure why this has a vote to close as “too broad.” This is actually an incredibly narrow description.– AdamantOct 9, 2016 at 0:11
I don't have an answer. I've been looking for the same story. My memory, though, has the scout actually looking "black and white" because the aliens based his appearance on Earth TV transmission which weren't in color.– Emsley WyattJul 15, 2017 at 3:09
I now DO have an answer, thanks to the folks at the Straight Dope message board. The story is called "No Place to Turn" and was in "Tales to Astonish #51" He is a reproduction of the final page. (Ironically in black and white)
It's a five page backing story and the online comic site only has the "Ant Man" story that opened the book.

Thank you very much! This story has been bugging me for years! Apr 11, 2018 at 4:27
You and me both. Glad to have an answer myself. Apr 11, 2018 at 4:31
