    Nonsense. My phone screen uses red, green, and blue to make up each pixel. The white pixels have their red component all the way at full brightness. Therefore there is a lot of red in the picture.

    You could also see this by opening up the image and looking at the red channel which would not be completely black.

      Texts on computers is made this way, so use a magnifying glass on black white text in a word document (for example) and you’ll see lots of colors. zoom in using the computer and you will still just see black/white.
