This is a Houdini SOP node asset that samples colors from an image.
Colors can be sampled with points on a line, on a grid, randomly scattered points or with input points. It's also possible to sample the most frequently occurring colors.
The sampled colors are stored in a color ramp and can also be exported to an image.
The asset is unlocked so the nodes inside can be edited.
