The values for color tables 10 and 11 of the Brewer color tables were swapped in the last update. The new version keeps YlOrRd as 10 and YlOrBr as 11, but makes the values correct. See below for what the color tables look like.
By the way, I was thinking of adding more color tables. matplotlib has more color tables that have a compatible license. Are there other color tables that people are fond of?
