Colours were to create a happy and upbeat feeling to match the beat of the music. When paired with the dark background it created a nice balance between the colours. Yellow and pink are colours that are very much associated with happiness, joy and warmth which suited the music very well.
For the overall visual design I wanted it to feel like with matched the music. The music used a low bass guitar with a repeated snap of the fingers through out. This made the video feel deep and a little rough. So I felt that a rough, grainy texture would be a perfect fit for the overall visual appearance.
