Colours

The colour red is involved in so many fast food resteraunt logos, because the colour red encourages appetite. Blue is supposed to diminish it. The McDonalds logo has the colour red an yellow in it, yellow meaning fun.

Amazon has an interesting logo. The word Amazon in written in black letters, with a yellow arrow pointing from the first letter to the last. This means that you can have fun from a to z.

Google also has another interesting logo. The letters are made up of blue, red and yellow, but the green is thrown in there to say, "we break the rules."

Red also encourages gambling and taking risks. Guess what Las Vegas's main colour is?

A company had to carry heavy black boxes. They were always complaining about the load. So, the company painted the boxes a light shade of green. The load hadn't changed, and yet the the workers felt like it was much lighter.
