In 2007 I thought of a pretty way to paint a square so that all pixels are different, but similar colors are clustered. For each pixel, set x,y to its coordinates; if their sum is odd, set the low bit … Continue reading →

fun with colors

Posted on Thursday, 2016 June 16 by Anton

Here, have a couple of Python scripts. Each creates an image file, 2^12 pixels square, each pixel of a different color. colorshuffle.py puts the coordinates of each pixel in Gray code, assigns each bit to one of the color channels, … Continue reading →

as many as it takes

allRGB: images in which each of 16 million colors occurs exactly once. (Found at MathPuzzle.) I see I’m not the only one to think of the Hilbert curve idea, but I’ll post two others. In unrelated news, I was surprised … Continue reading →

This image, which I made a few years ago, is based on a tiling of the hyperbolic plane with triangles whose angles are π/2, π/3, π/7. Other than the 7, which can be changed to any higher integer, I couldn’t … Continue reading →

My strip representation of the hyperbolic plane inspired Vladimir Bulatov to explore weirder conformal mappings thereof. (Conformal means angles are preserved.)

Hilbert’s palette

Posted on Wednesday, 2008 December 03 by Anton

A space-filling path through this square is matched to an analogous path through the color-cube. I had this idea in mind for years but the algorithm for Hilbert’s curve defeated me; then I stumbled on Steve Witham’s Python code, and … Continue reading →
