axes

Best Answer

There are so many properties you can set. for example:
plot(1:10);
ax = gca;
get(ax)  % Display what properties we can alter

The colors are in the range of 0-1 and in order r, g, b. So for example, red would be [1,0,0]. So to make a font size of 20 with the x labels being red and the y labels being blue, you'd add these lines:
ax.FontSize = 20;
ax.XColor = [1, 0, 0]; % X labels are red.
ax.YColor = [0, 0, 1]; % Y labels are blue.
