Have you ever noticed that all the logos for major fast food chains are in red, yellow or both colors? Yeah, I tried to figure out if there is any hidden symbolism or fast food psychology and discovered it had something to do with the psychology of colors and graphic design more than anything did.

In graphic design color classes, they define that yellow is supposed to be associated with quickness and speed while red is supposed to stimulate appetite. Color has direct physiological effects on the brain. Red increases pulse, blood pressure, and respiration while yellow is the easiest colors that can be seen from the longest distance.

So, what are we waiting for, let’s see how many fast food restaurants have their logos in the strong, attention getting contrast of red and yellow or any of the two colors.

Pizza Hut - Pull The fun out of your pizza:

Popeye’s Restaurant - Love that chicken from Popeyes:

Burger King - Have it your way:

Bojangles - Flavor without fire:

In-n-Out - Quality you can taste:

Mc Donalds - I’m Lovin It:

Wendy’s - Old Fashioned Hamburgers:

KFC - Finger lickin good:

Sonic - America’s Drive In:

Burger Chef - It’s All here:

However, many people still don’t agree to this theory of merging bright red and yellow for restaurants because they think these colors are not pleasant and relaxing, so those who choose to sit down to eat won’t stay long. What do you say…Does these colors really affect your appetite and tempt you to eat more?

Do write in to prove your point and let me know if I missed any of the restaurant logo in red and yellow.
