Hi, I think when you change the colour property, it applies for both the line and the error as shown in the below code:
x = 1:10:100;
y = [20 30 45 40 60 65 80 75 95 90];
err = 5*randn(size(y));
errorbar(x,y, err, '-or','LineWidth',2,'Markersize',3)
To apply different colour for error lines, you can code it as follows:
x = 1:10:100;
y = [20 30 45 40 60 65 80 75 95 90];
plot(x, y, '-.','LineWidth',1);
hold on;
err = 5 * randn(size(y));
errorbar(x, y, err, 'or', 'LineWidth', 2, 'Markersize', 3)
hold off
