MATLAB: Formatting the JET colormap

colormapcolormapeditorjet

I am familiar with colormapeditor but every time I type it in the command window, after setting colormap to jet, I edit the parula colormap.
Even after editing the parula in the command window it refreshes back to normal after running a loop.
I hope to resolve this issue, I want the jet colormap but for values that are 0 (the midpoint of my colorbar), the color should be white/or a light color as shown below, the rest of the color map should be unchanged. Appreciate any help regarding this question.

The colormapeditor changes the colormap of the current figure. It does not save or store the colormap in any way.
You will most likely have to follow a workflow something like this:
figure() % open a figure, or even better plot an image or something similar
colormap(somecolormap) % change to somecolormap
colormapeditor() % adjust the colors until you are happy
Once you are happy with the colormap continue by storing the colormap:
map = colormap(); % store colormap in an array
and then inside the loop use map to set the figure/axes colormap as required:
for ...
    fgh = figure();
    ...
    colormap(fgh,map)
end
