Here is another set of collages for Week 4 in different colour complements:
Here is a second set of collages from papers with a yellow to violet colour gradation. Now that I can see the pieces of paper I have left, I've become aware that I've been using very little of the papers which have white added to the colours. Not quite sure why. For both these and the orange to blue collages I ended up painting more papers with different values of grey.
There are 2 collages for each of exercises 1, 2 and 3 and 1 collage for exercise 4.
