Chroma - the intensity of a colour - the orange can be "diluted" towards yellows and towards reds, and by being darker or lighter. The blue can go towards green or toward purple, and again, darker or lighter. So there's a lot going on, and it's hard to evaluate the actual amount of "chroma" -
Next, trying to make the same colour look like different colours - lighter, darker, warmer, cooler - by putting it on different backgrounds. Some of these look more obvious in the photo than they do in reality. Though I think I understand the principle (it looks darker on a lighter background, warmer on a cooler background, etc), I can't really "see" it. Maybe this takes practice.
Finally, making two colours look the same. Do they?
Most people had done lots of homework, filling the pages of their colour sketchbook. Here's some Ann prepared earlier - "some colours just sing," she said.
I've done quite a bit of this work in the past and sometimes it is difficult to judge the differences/similarities in tone. I think you've come pretty close with getting the two colours to look the same on different backgrounds. Have you tried squinting your eyes up when you are looking? It does help to see tone more clearly.
ReplyDeleteWe did this with Ruth Izzard (sp?) The first effect becomes more apparent if you have bigger background bits, or smaller bits of colour (if that makes sense)
