Am new! Help with kitchen wall colour please?

[GlamGemini]

Am new around here, hello waves

Not my house, but my boyf's and kitchen is maple/oak type units, with black worktops, currently a grey floor, which maybe getting changed. Walls are magnolia, not sure what colour to do walls? He would like grey but would this work? We think its a west facing kitchen.

Hope someone can help with colour ideas? or suggestions for greys? we don't want to get it wrong!
Thank you very much in advance :)
