I like - for some reason it makes me think of virtual particles boiling out of & evaporating back into empty space...........

I love this technique .....the colors are applied to the canvas and allowed to dry well for a week or so then Lamp Black acrylic paint is painted on, covering the entire canvas....after a pause you use your palette knives to create the squiggles....it's rather magical watching the colors emerge from hiding...it's just fun to do......Ive often done "one line" paintings of the human form instead of squiggles with cool results

I'd never heard of that technique before... I've heard of "additive" and "subtractive" used in connection with musical composition, but I have NO idea what either means. Selective removal of the jet-black overlayer sounds "subtractive" - reminding me of how little I know!

My understanding of additive and subtractive has to do with mixing colors....so in the case of painting that would be subtractive yes.....additive mixing is used in digital screens and lighting....these models are not competitive but describe how color is created....colors work differently depending on whether your dealing with light, or with pigments....primary colors in the domain of digital graphics are RGB ( red, green, blue ).....whereas with painting the primary colors are RYB ( red, yellow, blue ).....additive and subtractive color-mixing boils down to the source of light.....basically the eyes have the ability to perceive color and the brain has the ability to decipher it.

Ain't art great ?
