Painting 27.4

Maximal hue difference: blue-purple and yellow

Maximal luminosity difference: that is, as much difference as possible, since the yellow should be both high-intensity and dark

Maximal intensity difference: very low-intensity blue-purple (by adding a lot of white, which also makes it very light) and high-intensity yellow by adding only enough black to make it dark compared to the blue-purple
