get rgv value from color name.
[Usage]
rgb_val = rgb_val_get(color_name)
[Input]
color_name : color name/namelist [string/cell string]
These short/long name can be used as color name.
'y' : 'yellow'
'm' : 'magenta'
'c' : 'cyan'
'r' : 'red'
'g' : 'green'
'b' : 'blue'
'w' : 'white'
'k' : 'black'
'o' : 'orange'
'db' : 'darkbrown'
'nb' : 'navyblue'
'sb' : 'skyblue'
'lb' : 'lightblue'
'br' : 'brown'
'yg' : 'yellowgreen'
'bg' : 'bottlegreen'
[Output]
rgb_val : rgb value (R G B) [Nx3]
The range of R/G/B is from 0 to 1.
[Example]
% get orange value
rgb_val = rgb_val_get('o');
rgb_val = rgb_val_get('orange');
% get multiple rgb value
rgb_vals = rgb_val_get({'y', 'm', 'c'});
