Colour duos and trios
The duos show every combination of two riso colours possible, from the colours we have available in our riso workshop. I made this to make it easier for the students to see possibilities in other colours than the first ones we think of, which tend to be the same ones.
The trios are not every possible combination, as that is almost 700 different possibilities. I chose a small selection of different combinations for this one, also to demonstrate that there is a lot to choose from and encourage students to expand their choices.
