Artists using black don't interest me, there are a lot of places were they are esteemed. Not here, this forum is for those that don't resort to blacks in any form. The best artists in the world.
I would like to see what you can do using the primaries and oppositions to make darks, you can compare the work in the two styles here if you like. I'm sure you will drop the black when you do, there really is no comparison.
I've painted with every medium, water oils are hard to wash out of brushes, you can't do it with water. As far as the media is concerned, it doesn't match many oil based choices, wax choices or pure acrylics as far as handling goes.
I see the blacks make bottomless holes, lots of them, all the same and all over the place. Both the camera and the computer remove the darkest colored darks because they can't record them.
