I would like to merge images so that pixels represent the RGB result of combining the overlays. In the simplest case, a yellow pixel + a blue pixel would result in a green pixel. Does ImageMagick support a mechanism to do something like this?

"yellow+cyan->green" occurs in subtractive mixing, like paints or colour printers. So do the work in CMY colorspace, eg:
Code: Select all
magick -size 200x200 xc:Yellow xc:cyan -colorspace CMY -compose Add -composite -colorspace sRGB x.png
