Move colorbar closer to figure?

I have a colorbar with no title that I need to move closer to my figure to reduce padding/white space between the figure and the colorbar. I've tried to experiment with position using the colorbar position properties but I'm striking out. Below is a snippet of code:
How can I adjust the colorbar toward the figure (in this case from bottom toward the top)?
hcb=colorbar('SouthOutside');
% Set the number of colorbar ticks and length of tick marks
set(hcb,'YTick',[-6:0.25:6],'TickLength',[0.01]);
% Label tick marks but only label every other tick mark
set(hcb,'YTickLabel',{'-6';'';'';'';'-5';'';'';'';'-4';'';'';'';'-3';'';'';'';'-2';'';'';'';'-1';'';'';'';'0';'';'';'';'1';'';'';'';'2';'';'';'';'3';'';'';'';'4';'';'';'';'5';'';'';'';'6'});
hcb.Ruler.TickLabelRotation=0;

hcb.Ruler.TickLabelRotation=0;
% move colorbar up slightly:
drawnow
hcb.Position(2) = hcb.Position(2)+0.01;

Ran in:
What figure properties are you setting? Only Position?
figure('position', [0, 0, 730, 1300]);
caxis([-6 6]); % R2019b
hcb=colorbar('SouthOutside');
% Set the number of colorbar ticks and length of tick marks
set(hcb,'YTick',[-6:0.25:6],'TickLength',[0.01]);
% Label tick marks but only label every other tick mark
set(hcb,'YTickLabel',{'-6';'';'';'';'-5';'';'';'';'-4';'';'';'';'-3';'';'';'';'-2';'';'';'';'-1';'';'';'';'0';'';'';'';'1';'';'';'';'2';'';'';'';'3';'';'';'';'4';'';'';'';'5';'';'';'';'6'});
hcb.Ruler.TickLabelRotation=0;
% store axes Position:
axPos = get(gca,'Position');
% move colorbar up slightly:
hcb.Position(2) = hcb.Position(2)+0.01; % back to 0.01 for a figure of this height
% restore axes Position:
set(gca,'Position',axPos);

Note that I changed the colorbar position adjustment from 0.03 to 0.01 for the tall figure. Colorbar units are 'normalized' by default.
