Colour use

I have been taking my colour use into consideration since studying it in Cop, colours have a different meanings and for this animation I plan to use positive colours so I have decided to use colours on the brighter side of the colour spectrum. Tints are what I am working with, I mostly am using gradients because I like the dark and light effect they give. I am not adding too much shade because I want my images to be light, bright and happy. I am focusing on making my images look realistic in terms of my colour use, need the colours to be normal, they need to reflect colours that you would see in real life.
