Change amount of ticks on a colorbar

Hi.
I have a 2D contour
contour(handles.Object,x,y,z,...)
where I set the colour map using an rgb matrix
b = (.23 .6 .8;...
.7 .8 .9;...
etc)
caxis([20 50]);
cbr = colormap(b)
colorbar
By default, the colorbar has seven ticks. What I want to do is create a colorbar in the range between 20 and 50 with a tick right at the bottom marking "20", one right at the top marking "50" and ticks marking 22, 24, 26, 28,... (steps of 2) inbetween.
If I type
set(cbr,'YTickLabel',{'20','22','24','26',[...],'50'})
the colormap only returns the first seven values in the positions of the initial five ticks.
Is there a way to manipulate the AMOUNT and POSITIONS of the ticks so that I can get a colorbar as described above?
Thanks!
Marc

Is there any way to set the number of ticks? I mean whatever the values are, I want always 5 ticks in the colorbar.
