We talked about several alternative colormaps at figure club last week. Here are links to a few of them on the Matlab File Exchange.
lbmap.m -- four Matlab colormaps from the Light & Bartlein Eos article that Sally wrote about. These colormaps are useful for communicating color to people with colorblindess (and those without, too!).
haxby.m -- a Matlab colormap to implement the Haxby scheme, often used on bathymetric charts.
cbrewer -- tools to implement colormaps from colorbrewer.org (more info in Sally's post).
cpt-city -- Nick sent us this awesome site with tons of ideas for alternative colormaps and color schemes.
Do you have any great color resources? Leave a comment!
