There's a fascinating reason behind the McDonald's logo being red and yellow

McDonald's is one of the biggest companies in the world. They are incredibly successful, with millions of dollars of purchases made around the world every day. 

And some of that success could be attributed towards something as simple as the colours of their logo. 

That's right, Macca's haven't made their logo red and yellow simply because they like the colours. There's actually a psychological reason behind it. 

Karen Haller, an expert in applied colour psychology has explained why McDonald's use these two particular colours on her website: 

"Looking at the positive psychology qualities of red & yellow in relation to the fast food industry, red triggers stimulation, appetite, hunger, it attracts attention.  Yellow triggers the feelings of happiness and friendliness.

When you combine red and yellow it’s about speed, quickness. In, eat and out again.

Yellow is also the most visible colour in daylight, which is why the McDonald’s M can be seen from a far distance."

She also explained why colouring is actually extremely important for a logo, writing, "The language of colour is communicated quicker to the brain than words or shapes as they work directly on our feelings and emotions."
