Generate m*n visually distinct RGB colors suitable for display. Useful when more than the 6 standard 'rgbcym' colors are needed for display. Generate m*n colors by sampling at constant intervals in HSV in the H and S channels (while keeping V fixed at 1). In addition, for every other level of saturation the H values are offset by half an interval to further distinguish each color. Inspired by a blog entry by Bart Mossey http://fob.po8.org/node/398, HOWTO: Picking "random colors". USAGE clrs = uniqueColors( m, n, [show], [offset] ) INPUTS m - number of saturation levels n - number of distinct hues to use show - optional display of colors offset - [1] offset every other row of colors OUTPUTS clrs - [m*n x 3] array of rgb colors EXAMPLE - standard 6 fully saturated colors clrs = uniqueColors(1,6,1); EXAMPLE - 24 colors used to plot some points clrs = uniqueColors(4,6,1); figure(2); clf; hold on; n=size(clrs,1); for i=1:n, plot(mod(i-1,6),i,'.','color',clrs(i,:)); end See also hsv2rgb, colormap, hsv, jet Piotr's Computer Vision Matlab Toolbox Version 2.51 Copyright 2014 Piotr Dollar.
