Parameters

Description

rgb2name returns the color name corresponding to the RGB values given by its argument. A vector of color names can also be returned if the color has more than 1 name. r, g and b must be integers between 0 and 255 corresponding to colors components red, green and blue. As usual 0 means no intensity and 255 means all the intensity of the color. RGB values can also be given by a vector [r,g,b].

If no color is found [] is returned.

The list of all known colors is given by color_list.

Examples

 
rgb2name(255,128,128)
rgb2name([255 215 0])
// get color #10 of the current colormap and find its name
cmap=get(gcf(),"color_map");
rgb2name(cmap(10,:)*255)
