It's a coloring book: color-by-number. If you pick lots of good colors, you get a pretty picture. Those are the hidden ONGs.
But if you pick only two colors, you can pass it off as an ordinary Time(afterTime)Frame. That's what the new mystery author did.
A clever OTTer was able to see the color-by numbers "under" the black (and white) regions, and saw that there were more than two different numbers. "What if we used more colors?
The real trick to getting two good
pictures is to use even more
numbers. In this particular case (one image with (say) 80 colors
, coexisting with another image with 2 colors
, is to use 160 numbers
. The first 80 numbers would be the regions where the b&w image was black, and the second 80 numbers would be where the b&w image was white. So, in the b&w image, 80 of the numbers would be black, and the other 80 would be white. But in the color image, there would be two different numbers that mean the same color (one with the secret black overlap, the other with the secret white overlap).
Try it with a real (paper) coloring book (or just a quick drawing). Draw two color-by-number images, one in B&W and the other in (four for simplicity) colors. Then put them one on top of the other and draw the resulting mishmash. Now, there will be regions where in one image it's black and in the other it's red. Call that "color #1". But where it' white in the first image and red in the second, call that "color #2". Etc:
red - black: 1
red - white: 2
blue - black: 3
blue - white: 4
green - black: 5
green - white: 6
yellow - black: 7
yellow - white: 8
Now, if you color the mishmash using the first column, you'll get your color image.
But if you color it using the second column, you'll get the B&W image.
