Astronomers use cameras that approximate human vision by combining red, green, and blue light to create "true color" images. However, these images are not always accurate for scientific research, which often requires analyzing individual color-filtered images to study objects' properties.

https://gbragafibra.github.io/gifs/collatz_ant_e20_dist_metrics.png
The user analyzes landscapes generated by an ant's trajectory, finding that stopping time and maximum distance from the origin are not sufficient to differentiate landscapes. The step at which the maximum distance is reached seems to provide discreteness, but cases of coincidence and exceptions remain unexplained.
