Error using patch not enough input arguments

I created 2 custom colors

>> myGreen

myGreen =

    0.0863    0.7294    0.7294

>> myOrange

myOrange =

    0.9216    0.8157    0.1294

I am trying to use them in patch like this:

    patch([x fliplr(x)], [yMean-ySEM fliplr(yMean+ySEM)],'FaceColor',myGreen,'FaceAlpha',0.2,'EdgeColor','none')

I have 3 arguments: x, y, and color. Why does it give this error?

Error using patch
Not enough input arguments.

The 'FaceColor' name-value pair is not necessary in patch calls. Just use the designated colour or RGB triplet as the third argument (that patch considered to be missing here) —

myGreen = [0.0863    0.7294    0.7294];
myOrange = [0.9216    0.8157    0.1294];

x = 1:10;
yMean = rand(size(x));
ySEM = rand(size(x));

figure
patch([x fliplr(x)], [yMean-ySEM fliplr(yMean+ySEM)],myGreen,'FaceAlpha',0.2,'EdgeColor','none')

Corrected typographical error.

Omit all parts of the command, which are not mandatory:

patch([x fliplr(x)], [yMean-ySEM fliplr(yMean+ySEM)])

Now compare this with the list of valid inputs taken from: doc patch:

patch(X,Y,C)

patch(X,Y,Z,C)

patch('XData',X,'YData',Y)

patch('XData',X,'YData',Y,'ZData',Z)

patch('Faces',F,'Vertices',V)

patch(S)

Your call does not match one of them.

Thanks did not know MatLab would read my RGB triplet and understand it to be color.
