Hello? Wait a minute! We are here to make artwork . . .that is to tune all the parts of a painting so that it arrests the viewer instantaneously. One of the ways that happens is to pay close attention to the darks and lights in a painting and arrange them into large shapes . . . . .that is to tie the darks together . . .or tie the lights to form big abstract shapes that will form a composition of values (lights and darks). This sort of attention to the pattern that is formed by the darks and lights leads to unexplainable abstract shapes that sit nicely, in an attractive way, into the rectangular shape of the canvas or paper. It is the relationship of the placement and the comparison of those large shapes to the rectangle that grabs a viewer.
If you think about it, this is really the basis for very good abstract paintings. . . . . .it is all about composing a great ratio of light within a dark matrix, or, the opposite, putting darks within a light valued matrix.
We are frequently misled by color . . . .that is that color so often resonates with us on an experiential level that we are not conscious of the fact that color has value . . . .that is that a blue can be very dark, or can be wispy light . . .or most other colors (save yellow) can do the same thing.
