That picture is quite well known (and even in the M1903 bible by Brophy), it just got colorized. Who knows what the original camoflage colors really were. Nice to see a suggestion on how it may had looked like. Original:
Painting black/white images is the task of an artist. Pieces of art contain the mind of the artist. Do not make the mistake to confuse this with assuming he knows what the colors actually were. While with colorization of war pictures the artists usually choose what actually might had been the look, but especially images like the one in question give them a certain choice with which colors they choose for camouflage of a stock. So take this as a piece of art where the artists using his freedom of art to pick specific colors.I often think, how do they know what the colors.
