It's kind of awesome. I realized it's like the opposite of perlin noise. Noise has large influential octaves, and smaller less influential "detail" octaves. The bayer matrix on the other hand has very minimal large octaves, and smaller octaves/iterations are as different/contrasty as possible.

Took me days to solve but I feel pretty accomplished now. smile:D smile:loveff:
Roses are #FF0000
Violets are #0000FF

I'm working on a complementary Dither filter (I know it's been done before but usually with scripts) that uses it, so I decided to release it as a snippet. I think I left the Add node unplugged, but for correct values it actually needs to be plugged in before the divide.



Hardest part is getting it to choose the closest color correctly. Some images look fine but then when you do calibration tests you can see that the algorithm is off.
Roses are #FF0000
Violets are #0000FF

This is really great and useful to have.

Technically perfect like the original Bayer matrix

This squares could be filled with colors or images

Quote
Wikipedia Bayer Matrix A Bayer filter mosaic is a color filter array (CFA) for arranging RGB color filters on a square grid of photosensors. Its particular arrangement of color filters is used in most single-chip digital image sensors used in digital cameras, camcorders, and scanners to create a color image. The filter pattern is half green, one quarter red and one quarter blue, hence is also called BGGR, RGBG,[1][2] GRBG,[3] or RGGB.[4]


Here is one bayer matrix with RGB colors
