I want the label color (i.e., of the text) to be a different color than the line color in xline and/or yline.
Is there an easy way to do this without the workaround below?
xline(5, '-', 'Text');
hold on;
xline(5, '-g');
hold off;

> The need is to make xlines and ylines...have lower contrast with the plot background color while having the label of the line have high contrast so the viewer can easily read it.
To achieve that, lower the Alpha value of the ConstantLine objects. This won't affect the label.
plot(peaks,'k-')
xline(10,'-k','Default Alpha')
xline([20:10:40], '-k', 'Lower alpha','Alpha',0.2)

Starting in R2024b, you can leverage the LabelColor property on ConstantLine to control the color of the label independently of the line.
x = xline(3, 'r', 'some label');
x.LabelColor = 'k';
