FOOD CHAIN OF YELLOW AND RED COLOR
You can't make them by mixing any other colors. Orange, green and purple are the secondary colors. A secondary color is made by mixing two primary colors. For instance, if you mix red and yellow, you get orange.
The idea is that red and yellow, in combination, make the perfect visual and psychological companionship for making us want to stop and eat. Red, which we know from research done in color psychology, makes feel warm, comforted, and loved. If a good meal should make us feel the same way, shouldn’t restaurants be using that color? After all, we don’t wan to feel cold (blue) while eating, nor do we necessarily want to feel jealous and fertile (green), evil and sad (black), or even exotic and artificial (purple) when eating our normal dinner. Sure other colors cause emotions that might be nice if attached to dinnertime (green can also make us feel lucky and purple can make us feel wise), but food is usually enjoyed most when it’s warm and when we’re with loved ones. Those two things make us feel comforted and comfortable; red is the best way to do this.
So why yellow? Yellow is cheery and exciting. It also grabs attention (we can see yellow from far distances really well–like those jumbo golden arches). Perhaps most interesting, though, is that research has shown the color yellow has the ability to speed up our metabolism! This means, in theory, when we’re around yellow we burn more calories. Does that make us want to eat more? Someone seems to think so...
And have you noticed how frequently it is coupled with the color yellow? Between red and yellow (often used together), you can account for the logos and color schemes of almost all major restaurant chains.
