In case you aren’t familiar here is the description from her personal web page –
ColorBrewer is a web tool for selecting map color schemes. It was reprogrammed by Andy Woodruff at Axis Maps. Links to another project apparently started in 2008 called Scale Master see here http://www.personal.psu.edu/cab38/ScaleMaster/ which has a host of other links and presentations but #19 is the Excel file titled “ScaleMaster for Proposed Design for Multiscale Topographic Mapping from USGS National Map Data, Cynthia Brewer and Chelsea Hanchett, Penn State Geography, July 2010”
Blurb from site:
ScaleMaster is a structured diagram for organizing multiscale mapping using multiple databases and design, selection, and generalization decisions.
In its rudimentary form, ScaleMaster is a do-it-yourself Excel file available for download (19. below). Other resources were listed and linked as we continued to develop the idea.
The ScaleMaster project was a collaboration among Cindy Brewer, Barbara Buttenfield, Larry Stanislawski, Lynn Usery, and Charlie Frye.
The research work was funded from 2008 to 2013 by the USGS Center of Excellence for Geospatial Information Science (CEGIS) through Cooperative Ecosystem Studies Unit (CESU) grants through geography departments at the Pennsylvania State University and University of Colorado at Boulder.
ScaleMaster research was initially funded by Esri through Professional Services Agreements 2003B6345, 2003B6346, 2003B6347 and 2006B2964.

See new developments with ScaleMaster from Guillaume Touya and Jean-Francois Girres, COGIT lab, IGN France (e.g., sourceforge; ICC2013 paper; CaGIS paper). The ScaleMaster approach is now popular with national mapping agencies.
