the <a href="https://s-rip.ees.hokudai.ac.jp/" target="_blank">SPARC reanalysis
intercomparison project group</a> for reanalysis comparisons. This
group carefully selected colors so that groups of reanalyses worked
well and so colorblind people could use it. The idea is that papers
will have these colors for time-series comparisons. Thanks to Cathy
Smith (NOAA/ESRL PSD and CU CIRES) for bringing it to our attention. <br></div><div><br></div><div>This is a 'color-blind' friendly color map that may be better than the hlu_default for drawing lines.</div><div>Beauty is in the eyes of the beholder.</div><div><br></div><div><a href="https://www.ncl.ucar.edu/Document/Graphics/ColorTables/Aid_in_color_blindness_cat.shtml" target="_blank"><b>https://www.ncl.ucar.edu/Document/Graphics/ColorTables/Aid_in_color_blindness_cat.shtml</b></a></div><div><br></div><div>===<br></div><div>I suggest that you create a table consisting of the RGB triplets and a corresponding named color.</div><div>The srip RGBs do not necessarily match the X11 table names but you can find 'close' colors'</div><div>These do not have the X11 named colors.
