I’m especially inspired by non-objective “Suprematism” championed by Kazimir Malevich and his contemporaries in pre-Revolutionary Russia, and generally inspired by 20th-century hard-edge and color-field paintings.
Color, in each of its dimensions, is vitally important – even in its absence. I don’t rely on a generalized characterization of colors. I rely on the juxtaposition of colors and values to convey potential impact. Any color rendered in paint seems ‘warm’ to me, because of the lusciousness of solidly applied paint.
For me, straight lines convey dynamism, simply because they move (and move the eye) directly and expediently from one place to another. Vertical lines are often divisive; horizontal lines evoke the horizon – and thus should be used sparingly (if at all) in non-objective compositions. Diagonal lines move the eye across two dimensions, and are thus inherently more dynamic. I often prefer positively sloped diagonals, because they may be hopeful to any viewer accustomed to reading from left to right.
It's trite to say that circles are “perfect” in their enclosure of space, but they are. Their constant radii are comforting, as is their association with eggs and with the womb. I paint circles as enclosures – more focused on the interior than the figure.
