I forgot to make one very important remark: Not everybody uses the same RGB colour values: this may lead to entirely different results, even if the same algorythm was used. Sometimes it seems better to alter the RGB values slightly. I thought of (...) (21 years ago, 13-Jan-05, to lugnet.build.mosaic)

Maarten, My mosaics are more than just a dithering of the 5 grayscale lego colors. In MLCAD, using a dithering of the 5 colors, I create a palette of 9 colors that I feel tricks the eye into seeing more shades, and therefore a clearer image. Here's (...)
