The found watercolors are all painted on a tinted paper approximately the color of the background on this website. The result is that the palette appears to be muted and dissimilar to Homer's. This was the main reason for presenting the various works on the Can You Solve This Puzzle? page in monochome - to remove that difference as a factor in separating the found works from the known Homer watercolors.

In the left colun below, I've taken the three known Homer watercolors from the Puzzle page and, using modern image processing software, simulated replacing Homer's white substrate with the tinted paper the found works are on.

In the right column, I've imposed the reverse process on the five found watercolors, simulating replacing the tinted paper with white.

Both methods are, of course imperfect, but are intended only to lessen an impediment to being able to compare the colors used in both sets of works, not as any sort of "proof".

The two columns scroll independently so any two sets of images can be compared side-by-side.
