I’ve now completed all the colour wheel hues to black. I had a lot of problems with the darker value colours and had to do several of them three times. As you said Jane, they go so quickly to black. When I did the course with paints, I only did two or three colours to black so I’ll be really interested to know whether the gradations are all roughly the same colours as with paints.
I’ve done four of the six complementary gradations and will hopefully get the other two done over the next couple of days. My ‘scuffed’ versions still need more work!
I’ve really enjoyed doing all these and have learned so much. I agree with Sue and with you that it makes you look at colours in Art, and also around you, much more deeply.
