The Color of Noise (2014)

Something sounds odd. If points are very close, they have high spacial frequency. If I reject points that are too close, I'm excluding high-frequency points and keeping only low-frequency ones. A distribution that favor lower frequencies and filters out higher ones is red, not blue. Am I getting it wrong?

I think the color terms and frequency may make sense in reference to a comparison against uniformly-spaced points such as a rectangular grid. If you perturb uniformly-spaced points with high-frequency/short-wavelength adjustments, you won't get the large-scale clumping that results from also including low-frequency/long-wavelength distortions.
