I simply filled in the shapes with a negative black colour, and placed them on a background of all the colours the car lights make.
I thought this series of shapes was really interesting. It gave me ideas for prints, paintings, and much more...I wanted to paint one of these shapes in large scale. I wanted it on a background similar to this. I wanted to show all the colours car lights make but at the same time show the movement within those colours..
I used a palette knife to give the paint movement and make the colours blend in with eachother. I reversed it so that the shape of the car light was negative and instead the background was made up of colour. I just used one of the shapes in this painting. I thought a simple shape against this chaotic background worked better.
