Hello,

I saw a nice visualization of medical image data [here](https://www.paraview.org/medical/) on ParaView’s solutions page and I was wondering if there is a freely-available medical image colormap (similar to those found in 3D Slicer) to reproduce these images. I checked [https://sciviscolor.org/](https://sciviscolor.org/) as specified in the paraview documentation, but the colormaps I saw were fairly generic and didn’t map onto CT/MRI intensities very well (white for high image intensity in CT, red for medium intensity in CT, etc.). Thank you!

This looks like the colour map called `Reds`, look for it in the [ParaView Default Colormaps](https://gitlab.kitware.com/paraview/paraview/-/blob/master/Remoting/Views/ColorMaps.json). There is also another one there called `Fast (Reds)`- not sure how to select it. Use “Choose Preset” in the "Colormap Editor to select `Reds`.

For VTK, this example: [JSONColorMapToLUT](https://examples.vtk.org/site/PythonicAPI/Utilities/JSONColorMapToLUT/) could be useful to you. It lets you generate a VTK color map from [ParaView Default Colormaps](https://gitlab.kitware.com/paraview/paraview/-/blob/master/Remoting/Views/ColorMaps.json) for C++ or Python, and also displays a cone using the colormap.
