OK, but why does McDonald’s use the colors red and yellow specifically?

He’s examined how specific hues can influence the way we feel, see, and think.

In a 2006 paper for the journalManagement Decision, Singh noted that the color red “stimulates appetite.”

The distinctive, cheery yellow of McDonald’s Golden Arches is also no happy accident.

Singh said that fast-food companies tend to use the bright attention-grabbing color to “hijack customers' interests.”

Haller also pointed out that yellow tends to connote “happiness, optimism, and friendliness.”

Plus, it’s the most visible color to the human eye during daylight hours.

A friendly place to eat that makes you think of happiness?

That sounds like someplace you’d like to be, right?

But McDonald’s isn’t the only fast food chain to use the colors red and yellow.
