with the default settings of pix_alpha white stays white and black gets transformed according to the background. red changes to pink, green to teal and blues stays blue. if I change the first two inlets from (0, 1) which is the default to (1, 0) then white becomes transparent and black gets transformed: red and green become yello and blue becomes white. I think the default color scheme on mac is some yuv dialect, so I tried pix_rgba, but that did not change anything. marius.
