Here’s The Real Reason Why All Fast Food Chains Have The Same Color In Their Logos

Drive down any highway and you'll quickly spot how the fast-food industry is seemingly obsessed with the color red. So much so, that even a flash of the hue evokes a feeling of hunger which can only be quenched by a McDonald's Big Mac or a KFC bargain bucket.

It's almost as though that splash of scarlet commands our taste buds in the same way that the color green infiltrates our conscience, causing us to inadvertently become more environmentally friendly.

Of course, the color green makes sense when connected with the environment, given that it is the predominant color with regard to nature.

But, the color red? How could that possibly connect to deep fat fried food?

Well, the thing is it doesn't.

The color red is simply just a bold, bright tone which catches the eye - a pretty significant element given that a majority of fast food joints were established near highways, with a busy flow of traffic passing by.

The signage on these restaurants needed to be eye-catching in order to entice customers through the door. Also, red is also the color of a stop sign. Coincidence? I think not.

Although, on its own, red is a little harsh on the eye. Something McDonald's clearly understood by incorporating the sunny color yellow into their iconic logo.

But they're not the only chain to add a touch of yellow into their logo, restaurants such as Burger King, Dairy Queen and Pizza Hut have all leaned on yellow, a color commonly associated with happiness, into their branding.

It's not a happy coincidence that all of the most major fast food chains have the color red in their logo. You don't have to be a psychology professor to know that there must be some science behind why the color red is so successful in the restaurant industry.

But you possibly do need to have some elementary understanding of how the human mind works to know just how it is possible for you to salivate every time you see the infamous golden arches of the McDonald's sign.

So here is the psychology. It's called the 'Ketchup and Mustard Theory' and basically, that means that the color yellow and red have the ability to encourage eating.

How can that be? Well, we subconsciously view the color yellow as a symbol of happiness, excitement and cheer. Meanwhile, red is perceived by the brain as a warning sign, triggering appetite and hunger.

In addition, red also makes us feel warm, comforted and loved which is vital when it comes to food.

Of course, in recent times McDonald's has adapted its color scheme, opting for a dark green tone instead of the alarming red that it is famous for.

This could be an attempt by the fast-food giant to align with a more environmentally friendly experience, or simply because they want to disassociate themselves from the gaudy red which made them famous, in an attempt to become more up-market in the world of fast food.

Whether the logo is red, yellow, green or blue, I know that I am guilty of loving it all equally. So pass me that chicken nugget and let's just enjoy the food!
