Sequential progression across several Qualitative categories? #18

I'd like to show Sequential progression across several Qualitative categories, in a way that the Qualitative categories do not visually conflict. It's not as simple as picking 2 Sequential schemes from ColorBrewer because they tend to look very similar at the low range.

Currently I can hack it by looking at Diverging color schemes, going out from the center one way and the other way gives me what I want for 2 Qualitative categories. I think my best bet for now is going center-out across schemes "RdBu" and "PRGn", which gets me up to 4 qualitative categories, but may not be colorblind robust across all the 4.
