File talk:Color map fs.png

Origin of the image

I have a strong suspicion that it's a (slightly cropped) negative of File:Color Funktion z.jpg, not a (purely) original work. Reasons for that are, first, unusual choice of cyan for positive numbers (Arg = 0). Second, there are some graphic details around the 0 point (i.e. the centre of the square) quite supportive to this theory. Incnis Mrsi (talk) 17:57, 22 November 2012 (UTC)
