As a photographer and videographer, I am a visual person, so this is why your colour scheme jumped out at me.

My main sense is that it is too pastel based - with the consequence that, whilst it looks pleasing to the eye, the action buttons don’t stand out.

Personally, I’d prefer a totally different look, but that is obviously a big ask!

I hope that helps you understand where I’m coming from - in terms of specific (new) colours, I am not sure - fir the simple reason that when I do this sort of thing (in my photographic work), I play around with many different combinations until I know that it is right!

Hope all this helps!

All good wishes,

David
