Replication of a colorbar in MatLab

Hello everyone

I am trying to impement this colorbar:

My attempt has been the following:

colorA=[192 148 92]./255;
colorB=[1 1 1];
colorC=[82 107 120]./255;
cmap3=vertcat(interp1([0 1],[colorA;colorB],linspace(0,1,numcolors/2),'linear'),interp1([0 1],[colorB;colorC],linspace(0,1,numcolors/2+1),'linear'));
cmap3(numcolors/2+1,:)=[];
cmap3=flip(cmap3,1);
clear colorA colorB color C numcolors

which I have done trying to pick the extremal colors at each side of the aforementioned colorbar. However, I obtain something like this:

without that nice blue color evolution on the right side of it. Any suggestions on how to get closer to the reference image?

I just reconstructed it from the image. See the attached file.

Z = peaks(100);
