You make not always see a noticeable difference but the brain will see the different blacks as more lively and not as dull and flat as they would be with plain black. It makes a difference even though you may not see it. The same goes for white, you can put very light tints in it that someone might not notice but they will still help keep the painting interesting.Anne & Jade, thank you!
The bg color is burnt umber so it sets a little bit to the orange side. I used ivory black (from rembrant) to the squirrel so it got quite black but I mostly mixed it with blue and where I saw reddish tone I mixed with cad red. This was a test and result is: I can't see as much difference in the different mixes as I had hoped. Should there be visible difference? To the dark accents I used ivory black directly.
