How can I set the color of text in a legend to match its corresponding line color in a MATLAB figure and change the Font size?

Hi, how can I change the color of the text for the legend so that each label matches its corresponding line color and the Font Size can be changed?

I would like to use this code:

[h, ~, plots] = legend('sin(x)', 'cos(x)');
for idx = 1:length(h.String)
    h.String{idx} = ['\color[rgb]{' num2str(plots(idx).Color) '} ' h.String{idx}]
end

But now I can not change the Font Size anymore! Can you give me an example how I can change the Font Size of the text in the legend?

Thanks for your support.
