Course work: After a final session of grey-scale adjustment the scale may still be weighted a bit toward black, but at least the steps appear even to my eye. A lengthy session of placing colored squares, squinting, and replacing them finally resulted in the arrangement that best seems to match color tone with greyscale tone, so I then glued them in place.
I then constructed the grid for Stage 2, and painted the columns for lemon yellow and cadmium yellow, using a violet mixed with alizarin crimson and ultramarine blue as the complement. The neutral colors mixed with lemon yellow and violet tend toward green; those mixed with cadmium yellow and violet tend toward orange. Colors quite near the umbers can be produced with each yellow, and a usable yellow ochre substitute emerges in the cadmium yellow column.
