I want the user to choose a color from a menu for my object. Can someone please suggest what the best way to do it is?
My object is in another function which I have called in the main script. The menu is also inside the function.
Part of Function:
Auto.Farbe = menu ('Wählen Sie eine Autofarbe aus' ,'Red','Yellow','Green');
Main script:
Farbe = Auto.Farbe;
patch('Vertices',Auto.Ecken,'Faces',Auto.Karosseire_Flaechen,'FaceColor',Farbe)
Any leads will be highly appreciated.

Perhaps something like this:
M = [1,0,0;... red
1,1,0;... yellow
0,1,0]; % green
X = strcmpi(Auto.Farbe,{'red','yellow','green'});
Farbe = M(X,:);
Or else download this:
https://www.mathworks.com/matlabcentral/fileexchange/48155-convert-between-rgb-and-color-names
and use it something like this:
[~,Farbe] = colornames('CSS',Auto.Farbe)

Do you want your users to select colors by name or by appearance? If the latter use uisetcolor.
