From MatPlotLib 2 and 3:
  • the default sequential colormap VIRIDIS (as well as INFERNO, MAGMA, and PLASMA).
  • the default line colororder TAB10 (as well as TAB20, TAB20B, and TAB20C).
  • the perceptually uniform cyclic colormaps TWILIGHT and TWILIGHT_SHIFTED
  • the colorblind-friendly sequential colormap CIVIDIS.
For MatPlotLib 2.0 new perceptually uniform colormaps were generated in the CAM02-UCS colorspace. The process is described here:
The default MatPlotLib colormap was changed to the newly created VIRIDIS, replacing the awful JET/RAINBOW, and the default line colororder changed to VEGA10 (note that the VEGA# colormaps were renamed TAB# in MatPlotLib 3).
The colormap data is available here and the line colororder data here
%% Plot the scheme's RGB values:
%% New colors for the COLORMAP example:
load spine
%% New colors for the SURF example:
[X,Y,Z] = peaks(30);
Axes ColorOrder Examples
%% PLOT using matrices:
N = 10;
X = linspace(0,pi*3,1000);
Y = bsxfun(@(x,n)n*sin(x+2*n*pi/N), X(:), 1:N);
plot(X,Y, 'linewidth',4)
%% PLOT in a loop:
N = 10;
X = linspace(0,pi*3,1000);
Y = bsxfun(@(x,n)n*sin(x+2*n*pi/N), X(:), 1:N);
for n = 1:N
ssplot(X(:),Y(:,n), 'linewidth',4);
hold all
%% LINE using matrices:
N = 10;
X = linspace(0,pi*3,1000);
Y = bsxfun(@(x,n)n*cos(x+2*n*pi/N), X(:), 1:N);
