The three girls are a great theme for the new experiences of color printing realized by the artist in 1918. He used a mixing of woodblock for the black scars in sky and road, and of three to four zinc plates for the lithography of colors. The chosen format is 50 x 42 cm.
Before printing the colors, Munch tried several variations by hand coloring black and white prints. One of them, with four colors in a rather lugubrious arrangement, was sold for $ 845K including premium by Christie's on October 29, 2013.
On September 29 in London, Sotheby's sells a color print of The Girls on the bridge, lot 66 estimated £ 200K.
In this version, the artist used the green, the blue and a strident red-orange that draws attention to the strong point of the composition. This red drowns any detail from the middle dress in a striking contrast of blood between the clear and dark clothing of the other two girls. Their attitude does not differentiate their feelings. Red extends the silent anguish to the entire group.
