Colors in Matlab

RGB colors

For coding purposes colors are mostly specified in RGB, which stands for Red, Blue and Green. The values range from 0 to 1. As an example: the color red is given by the triple [1,0,0]. Since it is hard to know what a certain triple (e.g. [0.5, 1, 0.5]) stands for it is more easy to call them by their name.

We have created a few functions for RGB colors by their names:

• <RGBcolors> for english names
• <RGBkleuren> for dutch names
• <RGBfarben> for german names
• <RGBcolores> for spanish names

A few examples:

>>colores.AZUL_CLARO
ans = 0.5000   0.5000   1.0000

>>kleuren.FELROZE
ans = 0.5000   0.5000   1.0000

>>farben.BLAU
ans = 0.0000   0.0000   1.0000

>>colors.LIME
ans = 0.0000   1.0000   0.0000

All the named colors are:

Color maps

You can make a color map for plots:

map = [RGBcolors.LIME, RGBcolors.BLUE, RGBcolors.MAGENTA];
colormap(map);
surf(peaks);
