An Interesting tutorial

The other day I had a tutorial on typography and colour in graphic design. I found the colour aspect very interesting. We were shown part of a picture, which you can see below.What do you think when you see this?......................  Of course, Cadburys.  This explained how established brands don't need to keep rethinking a new logo. If they are consistent, they are more recognisable. Cadburys are very well known amongst all generations for their colour "purple". Therefore, they only need to have purple somewhere in their adverts for us to know it's them. The same goes for this advert 

Coca Cola has the same advantage. With the colours red and white and it's distinct typography, we immediately recognise this worldwide brand. I will be researching the psychology of colour and how different colours effect peoples mood and well-being.
