Maxfield Parrish painted his most famous work Daybreak in 1922. It appeared on several editions of art prints and on the cover of Coy Ludwig’s book from 1973. That book, and all those prints in antique shops have a decidedly “Parrish Blue” tonality (bottom image).

In all the reproductions since then, it has a much more golden and violet appearance (top image). I saw the original when it was shown at the Norman Rockwell Museum retrospective exhibit, and it really did have that golden/violet appearance.
If you put the two side by side, at first glance it seems like a difference in color balance. Maybe all the early prints were wrong, printed from a transparency that was shifted too far into the blue range.
Maybe all the warm colors faded out of all the reproductions. Maybe the “Maxfield Parrish blue” was never there in the first place, and was a consequence of bad reproduction. But Parrish personally approved the early reproductions.


And where the values of the blue shadows in the far mountains used to be much lighter than the bending figure, now they’re darker and more uneven (3). Changing the color balance sliders shouldn’t affect the value organization.
Is it an alternate version? Parrish dealer Alma Gilbert, in her book on Parrish’s Masterworks, referred to rumors about a second version, but put them to rest with the confirmation by Parrish's son upon seeing the painting again in the 1970s.


I don’t know the answer. It’s kind of a mystery. Maybe some of you can shed more light on it.
