The bleach one slightly reduces front loaded friction (ie. don't need to learn it) at the expense of being less legible, harder to print cleanly, less robust to fading and uglier. The others don't even really have the first benefit. Which is exactly in line with 'good' ui design in software. So goal achieved, I guess.
