The calibration of my monitor is probably to blame. Onscreen colors are lighter and yellower than default. To reduce eyestrain. Grays contrast from blacks much more.

I'm looking at the version of level 1051 that my color printer produced. You're right, 1051-c1 is blendy. Maybe my idea is a good idea anyway? Maybe we should try a cascade like that someday. Don't tell me, let me guess... it has already been done.
