BREWERMAP provides all ColorBrewer 2.0 colorschemes for MATLAB, with simple selection by colormap length and colorscheme name. Alternatively the colorscheme name can be preselected, after which only the colormap length is required to define an output colormap.
BREWERMAP is compatible with all MATLAB functions that require a colormap. The function consists of just one M-file that provides all of the ColorBrewer 2.0 colorschemes (no mat file, no third party files, no file-clutter!). Downsampling or interpolation or repetition of the nodes occurs automatically, if required.
% New colors for the COLORMAP example:
S = load('spine.mat');
% New colors for the SURF example:
[X,Y,Z] = peaks(30);
% New colors for the CONTOURCMAP example:
brewermap('PuOr'); % preselect the colorscheme.
load topo
load coast
worldmap(topo, topolegend)
contourfm(topo, topolegend);
contourcmap('brewermap', 'Colorbar','on', 'Location','horizontal',...
'TitleString','Contour Intervals in Meters');
plotm(lat, long, 'k')
% Plot a scheme's RGB values:
rgbplot(brewermap(NaN, 'Blues')) % standard
rgbplot(brewermap(NaN,'-Blues')) % reversed
% View information about a colorscheme:
[~,num,typ] = brewermap(NaN,'Paired')
num = 12
typ = 'Qualitative'
% Multiline plot using matrices:
N = 6;
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)
% Multiline plot in a loop:
N = 6;
X = linspace(0,pi*3,1000);
Y = bsxfun(@(x,n)n*sin(x+2*n*pi/N), X.', 1:N);
for n = 1:N
plot(X(:),Y(:,n), 'linewidth',4);
hold all
Bonus Functions
BREWERMAP_PLOT creates a figure which shows the nodes of all ColorBrewer colorschemes.
BREWERMAP_VIEW creates an interactive figure that allows selection of the colorscheme, and has two colorbars showing the colors of the colormap and the grayscale equivalent.
R2014b or later: BREWERMAP_VIEW can also update other axes' or figures' colormaps in real time, for example:
S = load('spine');
R2019b or later: BREWERMAP_VIEW can also update other axes' or figures' colororders in real time, by setting the 3rd input to TRUE:
The function BREWERMAP:
  • Consists of just one convenient M-file (no .mat files or file clutter).
  • Has no third-party file dependencies.
  • Has no special toolbox dependencies.
  • Requires just the standard ColorBrewer colorscheme name to select the colorscheme.
  • Accepts the colorscheme name as a string scalar or a character vector.
  • Supports all ColorBrewer colorschemes.
  • Outputs a MATLAB standard N-by-3 numeric RGB array.
  • Uses a default length the same as MATLAB's colormap functions.
  • Is compatible with all MATLAB functions that use colormaps (eg: CONTOURCMAP).
  • Includes the option to reverse the colormap color sequence.
  • Does not break ColorBrewer's Apache license conditions (unlike many on MATLAB File Exchange).
This product includes color specifications and designs developed by Cynthia Brewer ( See the ColorBrewer website for further information about each colorscheme, colorblind suitability, licensing, and citations.
