The idea with these paintings (closeups above, full images below) was to have lower layers show through a mostly transparent top layer.
You can see the effect best in the blue closeup above: the black shading is on the lower layer, below the one with white highlights.
The blue painting (48 x 60 inches) is pretty boring, but I wish I'd held onto the other one (40 x 32 inches?). The picture here is terrible -- with uneven light from the flash and dark blue digital artifacts in the corners -- but I like the painting's frosty look.
