The rose is an inexhaustible symbol in art history, which, among other things, served as a model for window rosettes in medieval cathedrals. Evard also frequently engaged with the symbol of the rose in his career and also presented it in a constructivist way. For example, he sent his masterpiece, the Roses Bleues from 1924, on a tour, where it was exhibited, for example, in the Parisian Salon des Indépendants.
The special feature of this painting is the subtle fusion of the red petals with the green background. At first glance, it is just an ordinary depiction of roses, but on closer inspection, it becomes clear that the green background shines through the roses. This gives the roses a diaphanous, fragile character.
