Hi, I have following error, which I don't know why it is occurring:
Error using plot
Bad property value found.
Object Name: line
Property Name: 'Color'.
I have many customized colors that I use via a cell:
cl={'w','bla','blat','w2','ora','orat','w3','sbl','sblt','w4','bgr','bgrt','w5','yel','yelt','w6','blu','blut','w7','ver','vert'};
plot([ xx fliplr(xx) xx(1)],[0 0 1 1 0],'color',cl{M{1,m-1}(q)+1},'linewidth',12)
Thanks!

What is the value of M{1,m-1}(q)? Try this
M{1,m-1}(q) % Spit out to command window
fprintf('M{1,m-1}(q) = %d\n', M{1,m-1}(q)); % Again as integer

It looks like you are passing a string into the color command and not the RGB value:
i.e. you are doing:
plot([ xx fliplr(xx) xx(1)],[0 0 1 1 0],'color',cl{M{1,m-1}(q)+1},'linewidth',12)
where cl is a string. It is not being evaluated to the RGB you want. While in theory you could "eval" the string - I would not recommend that approach.
A much better solution would be to use a matrix or cellarray containing the colors. Or you can use your current approach (using names) with a structure:
myColors.sbl=[0.35 0.7 0.9]; % skyblue
myColors.bgr=[0 0.6 0.5]; % bluish green
Then access the colors by using dynamic fieldnames:
plot([ xx fliplr(xx) xx(1)],[0 0 1 1 0],'color',myColors.(cl{M{1,m-1}(q)+1}),'linewidth',12)

Where did you get all those color names? I don't think they're ones that are recognized. Try simple things like 'r', 'y', 'k', etc. as well as 3 element arrays with values between 0 and 1, for example [.2, .3, .7].

No. Because you're putting the name of the variable in there, not the variable itself. It has no idea that the string 'blat' is the name of some variable you created.
