Origin of the Color of Cv. 'Rhapsody in Blue' Rose and Some Other So-called “Blue” Roses.
Jean-François Gonnet

Cyanin is probably "trapped" into AVIs at higher concentrations than would be possible in a vacuolar solution and in quinonoidal form, appearing purple-blue because of additional absorption in the 580-630 nm area. Quite similar pigmentation features were found in very ancient rose cultivars (cv. L’Evêque or Bleu Magenta), also displaying this type of so-called "blue" color.

Bleu Magenta. This rose reached me from the Roseraie de l'Haÿ near Paris, but I have been unable to trace the name anywhere. This is unfortunate, since it is that largest in flower and the richest in colour of the purplish ramblers. Fully double the flowers in dense clusters, darkest violet-crimson fading tom dark parma-violet and grey, with an occasional white fleck. Practically scentless. Shining dark green leaves on nearly thornless green wood. An effective garden plant. About 15 feet. The last to flower of the purple ramblers.
