Not Black-and-White

Images we have always called 'black-and-white' have been called that incorrectly since the medium was begun over 150 years ago. Look closely at these images and you might notice that all the colors of the spectrum are represented in the photo . . . often excepting only full-out black and full-out white. You have seen images in black and white, of course, but the term for that is 'silhouette.'
Greyscale in the term that works best, with all colors being represented by shades of grey on a scale between the rarest of colors, total black or total white.
No more vocabulary, for now, just a few more greyscales.
