ParaView indeed lets you create color maps for your use case, but it's a tad awkward. One can specify duplicate control points, each with a different color. This makes it possible to have a sharp transition at particular values. I have attached an example color map for your use case. Import it by opening the Color Map Editor and clicking on the Choose preset tool button (the folder with a heart on it). Then, click Import in the bottom left corner and load the file.
By the way, we recently transitioned to a discussion forum, https://discourse.paraview.org. Please use that forum for other ParaView questions.
