Change color of numbers at colorbar

Hey, is there a way to change the color of the written numbers at the colorbar? I don´t want to chance the colormap, just the color of the numbers at the color axis.

Undocumented property -- underneath is a NumericRuler object which does control the axes ticklabels independently.

figure
surf(rand(5))
colormap(turbo)
hcb = colorbar;
hcb.Ruler.Color='b';

yields

And, you can set

hcb.Color='r';

afterwards and not destroy the label colors but change the box outline only.

I've railed over and over about the penchant for hiding properties that TMW seems to get more and more enamored with...

Awesome. Yes, I would have never found this :D

Best thanks

Changing either Color or Ruler.Color changes the other one as well; they are linked together. And it affects the box color as well as the label color.

Au contraire, good buddy...

surf(rand(5))
hcb=colorbar;
hcb.Ruler.Color='b';
hcb.Color='r';

leaves the tick labels blue while only the box turns red.

Changing the Color property alone/first does both, setting the Ruler.Color first breaks the link if address the other later as the above illustrates.

hcb=colorbar;
hcb.Color='r';
hcb.Ruler.Color='b';
hcb.Color='r';

turns both red first, then the labels blue. But it also leaves the same image as the above -- once the Ruler.Color is set, it's sticky.

Ah!

I HAD tried this before I made the comment... :)

That there isn't a FontColor to go along with rest of font properties is the oversight -- not only here, but fairly globally.

surf(rand(5))
colormap(turbo)
hcb = colorbar;
hcb.Ruler.TickLabelFormat = '\\color{red}%g';

The double \\ is important for this purpose.
