Makie: nonlinear color levels in Colorbar

[Datseris]

The replies I’ve gotten at this post will help you make a nonlinear / nonuniform color scale I believe

Custom divergent colormap with unequal sides

I am working with Makie.jl and I wish to create a custom colormap. Taking any divergent colormap provided by Makie, such as :balance for example, I want to make a colormap that has the same colors as :balance or :delta, but the left side spans the range of values 0-1, and the right side spans the range of values 1-4 (instead of what the symmetric 1-2 would dictate). Is that possible? If yes, how?
