Spectrogram colormap

The new spectrogram colour pallet is growing on me…
Can someone supply the colormap in RGB so that I can use it in Matlab?
The map will have three columns for Red, Green, and Blue like this (for “jet” which goes from dark blue to green to dark red):
0 0 0.5625
0 0 1.0000
0 1.0000 1.0000
1.0000 1.0000 0
1.0000 0 0
0.5000 0 0

Hi TideMan—these may work for you:

If not, then you can find the RGB for the four perceptually uniform and linear Python colormaps here:

Thank you Ian. The Matlab File Exchange link worked for me.
