Since I ordered two sets (delivery on 29.04.2015) and the color separation was equal to, here for those interested: 1x 16 studs in red 2x 12 knobs: each 1x yellow, green 18x 8 knobs: each 3x red, orange, yellow, light green, green, blue 25x 6 knobs: each 4x red, orange, yellow, green, blue and light green 5x 54x 4 knobs: the 10x red, orange, yellow, green, blue and 4x green In the photos, the colors are sometimes different, so I guess that can fundamentally change again. But I would assume that the current compilation is by design and is therefore tended to be remain so.
The colors correspond to the current Duplo colors (from ~ 2005?). When all closer look, there are of course minor differences (mainly in the light reflection), but these do not sting the eye. (The differences are smaller than those caused in the course of time at Lego by sunlight.)
The stones are absolutely compatible and feel no different from Duplo to.
(Case you wonder: The patents have expired a few years ago, therefore any Duplo now must imitate - completely surprisingly but not everyone puts the same amount of emphasis on quality ...)
