Darker colors correspond to the lower range of [0,1] of the RGB scale.
r=5;
str = compose('x^%d',1:r);
hold on
for k=1:r
col = (randi(128,1,3)-1)/255;
fplot(@(x) x.^k, 'Color', col)
end
legend(str)
However, as you can see that it while they are different, it is difficult to easily distinguish between them.
Aternatively, you can use the inbuilt color map available in MATLAB, to have distinct colored plots.
figure
hold on
map = hsv(r);
for k=1:r
fplot(@(x) x.^k, 'Color', map(k,:))
end
legend(str)
You can check out all the available colormaps on the documentation page - colormap and choose according to your liking.
