Yup, and we don't use a rainbow colormap by default anymore! We do provide a few custom ones that were developed with viscm, which I believe was used by in development of viridis, magma, etc. I think the specific examples are all from the published literature, and we accepted them as submitted by users -- but a refresh would be good!
