If you like neutral colours, I recommend shades of brown for the feature wall and white or cream colours for the rest.

I think a light grey would enhance your table and chairs. You can add accents of brighter colours in small touches (kitchen herbs, fruit bowl,...) and some art on the table wall? The kitchen looks quite dark, you could consider letting more light in by leaving the blinds up and maybe change the ceiling lighting to halogen spots?

F&B Skimming Stone?

If you do find it a little top heavy, I would be tempted to soften the green colour very slightly - have a look at earthborn colours they have some lovely ones I think you'd like, Sunday Stroll and Gregory's Den being the best I think for you. If it helps, really think about how you want the room to feel when you're using it, light and airy/statement and impactful/calm and relaxing/luxurious and elegant/industrial and rugged? - that will help you dress and finish the space too if you keep this in mind whilst choosing your finishes. The tiles have a yellow undertone to them and the gorgeous, sumptuous green colour you have chosen looks like it has a slightly blue undertone so it's just a case of balancing the two so that the walls don't overpower your cabinetry :). If you're happy keeping the heavier green maybe tint the ceiling colour with green, just a touch to soften the ceiling line? Exciting project! Good luck!
