Hmm. If they can't give you the exact shade of blue you want, then I would either (a) do all white cabinets or (b) pay a bit more for a cabinet brand that will allow custom colors. Neither of those blues work, IMO. The light blue is a little too baby blue and the other is a little too periwinkle (at least on my screen). Ideally, you'd get a gray blue:
Something like Benjamin Moore's Van Cortland Blue would be beautiful:
Or try BM's Gossamer Blue:
