Lost in a colour wheel

You might be wondering where I am with my Master Spinners homework. Well, I am stuck in a viscous circle - the twelve colour wheel circle. It is not hard, nor boring, nor tedious, it is just taking time. The assignment: Create a colour wheel. It requires weighing each colour, then blending colours equally by weight, then spinning them and finally create a colour wheel. Here's how it works: take three primary colour merino roving - yellow, blue and red. Blend each of the primary colours with another primary to get three more colors, eg. red + blue = violet. Keep in mind that the new blend has to be homogeneous - blended very carefully, striped colours will be rejected. So I card very careful using the drum carder, running the new blend through the drum 3 - 4 times. Then take the new colour (or, figure out the correct portions of the primary colours that produced the new colour and add to it to et the new colour - you can see where this is getting confusing) and blend with the primary on each side eg. violet + blue = violet/blue, violet+red= ...hey wait a minute, what does that make and where is it? Excuse me while I card more wool....
