I think the colour used on these cabinets is great. This is a colour which is unlikely to unsettle anyone who sees it and is teamed with very neutral walls and furnishings. This room looks modern, with a little retro or Scandinavian twist.I believe that if you really love a particular colour, why not use it as a colour block on cabinets. Just keep the main elements in the room neutral and the accent colours to a minimum, like the orange accent used here.

I'm not 100% sure what you're asking, but if you're looking for suggestions whether to make the lower cabinets grey and the upper cabinets white or vice versa, then I would be tempted to make the lower cabinets grey. I think this would help to make the ceiling feel higher and the overall space larger and brighter. But, it may depend upon what style you're going for, whether you have an island benchtop and, if so, what material/colour will be on the rear/exposed side of the island benchtop, the amount of natural lighting, etc. You can easily search through Houzz photos by room, size, colour, materials, etc. Here are a few examples I found from a quick search which may help:

I would personally stick to white cabinets... I know, not very original... but I think white works best with timber benchtops... and black/white/timber is a fail-proof/timesless combo imo... But if you wanted to inject a bit of colour... and based on your coastal theme description... then I would suggest maybe duck egg blue?... do a search of "duck egg blue kitchen" in photos on Houzz AU
