Is there a way to plot two or several matrixes in one Diagramm using the same collor for respectively two Graphes?

load Test2_-4-0.mat
A={pts.z,pts.voltage}

load Test2_0-4.mat
v=flip(pts.z)
B={v,pts.voltage}

A1=[A(:),B(:)]
plot(A1{:})
legend('v1','V2','opt','lin')

While the matrices A and B are:

Is there a way to tell Matlab it should relate to each column of the pts.voltage matrix (41x4) a specific color (or always the same color)? So two graphes have the same color.

Or some other soloution?

Without using too much code for example like:

plot(z,x(:,1),'r',z,x(:,2),'b',z,x(:,3),'g',z,x(:,4),'m')
hold on
plot(v,y(:,1),'r',v,y(:,2),'b',v,y(:,3),'g',v,y(:,4),'m')
hold off

The default colororder has 7 colors in it, and each series uses the next color in the colormap. Once the 7th line is used, the colororder starts over at color 1.

z = 1:100;
x(:,1) = z/10;
x(:,2) = sin(z);
x(:,3) = z/5;
x(:,4) = cos(z);

y = -x;

plot(z,x,z,y)

If you do not want to specify the color, then the next option is to set the colororder using only 4 colors.

newcolors = [0.83 0.14 0.14
             1.00 0.54 0.00
             0.47 0.25 0.80
             0.25 0.80 0.54];
figure
colororder(newcolors)
plot(z,x,z,y)
