Converts color name or hexadecimal color code to an rgb triplet. Optionally a second argument can be passed defining the desired opacity level within [0,1].
A rgb triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities are in the range [0,1]; for example, [0.4 0.6 0.7].
A hexadecimal color code is a character vector or a string scalar that starts with a hash symbol (#) followed by three or six hexadecimal digits, which can range from 0 to F. The values are not case sensitive. Thus, the color codes '#FF8800', '#ff8800', '#F80', and '#f80' are equivalent.
color % shows color picker.
% without transparency
rgb = color(name) % converts color name to an rgb triplet.
rgb = color(hex) % converts hexadecimal color code to an rgb triplet.
% with transparency
rgbo = color(name, 0.3) % converts color name to an rgb triplet plus opacity.
rgbo = color(hex, 0.3) % converts hexadecimal color code to an rgb triplet plus opacity.figure('Color', color('ghost'));
