hello

I believe you want to have larger font for a better reading

simply create a handle associated with the colorbar and then you can modify any proprerty

example (a bit exagerated)

figure
peaks(25);

hcb=colorbar('ver'); % colorbar handle
hcb.FontSize = 15;
hcb.Title.String = "GDP range";
hcb.Title.FontSize = 20;
