Abstracts
These rule-based abstracts, in different formats, are all produced by dividing the surface into regions and, using only primaries, overlaying colours according to a set of rules.
Square format
Take yellow (or blue, red, green) as the base brightness
Divide the picture equally in the horizontal and vertical direction
Vertically, lay green left and red to the right
Horizontally, overlay yellow above and blue below
Adjust to attain quadrants of equal brightness
Rectangular format (union and division)
Select perceptual opposites (red/green or yellow/blue)
Divide the picture horizontally
Lay red above green (or blue above yellow)
Overlay blue or yellow (or red or green) over the entire surface
Adjust to attain regions of equal brightness.
Painting plan
Stripes (Square format: 2 in painting plan to the left)
Divide the picture surface horizontally
Paint half cadmium yellow and the other ultramarine blue
Divide the regions in 2. and paint yellow and blue
Divide the regions in 3. and paint yellow and blue
Separate yellow/blue regions by white stripes.
Painting plan
Stripes (Long format)
Paint according to the painting plan (at left)
Produce three combinations yellow/red, yellow/blue and red/blue
Note in the painting plan, that the upper half of the picture surface is painted in cool and the lower in warm colours
(The far right picture compliments the second, but the upper halves lower half of the picture surface are painted in combinations of warm and cool colours (e.g. in the upper half lemon yellow and ultramarine blue)
Stripes (Long format: two combinations interlaced)
As for the other stripe paintings, these painting employ the same system for overlaying a contrasting colour over another, e.g., red/yellow, but here the paintings involve two such combinations interleaved. For example, in the image red/yellow and blue/red.
