Fast, fast food.

Notice any similarities??? Why all the red, yellow and blue! I believe there are a few explanations.

One- primary colours are bold and grab our attention easily. They are also relevant and recognisable to pretty much anyone. Can you imagine Maccas rebranding to a specific shade of muted lime green? No one would really relate!

Two- These colours actually make us hungry! Red in particular is supposed to... I suppose it sort of makes sense. Red to me promotes urgency, so if I'm really hungry then I supposed red would reinforce that feeling and make me want to get food from there.

Junk food companies are tricking us via carefully planned colour psychology!!!
