My friend had a bet with someone that she couldn’t find a fast food logo that doesn’t have yellow or red. And we thought for sure Whitecastle was the winner, until I looked it up online, and found it has yellow. It almost makes me want to start up a chain and not have red and yellow, and then it would probably fail, because it wouldn’t catch anyone’s attention! ha

There are color theories that red and yellow are used to catch attention. So it makes sense that fast food chains want to catch our attention and stop to eat there. Red is used on stop, exit, and wrong way signs; yellow for danger and caution signs. Being dangerous colors, others might say they should warn us not to eat at fast food chains since they are dangerous to our health.

I found an interesting more in-depth article on red and yellow color theories on aiga.org.
