DSDN 112: colours for icons

Today we got told in the lecture that colours for our icons have to represent the icon and we can't just choose whatever colour we want because they look good with each other. For example like traffic lights, the green means go and red means stop, we can't just switch those two colours around with what it means because they aren't the colours to show it. So for my colours I'll have to choose them wisely and make sure they do represent the icons on my navigation.
