I prefer the green range of colours, possibly with minimalist effects in dark blue to get contrast.
With regards to the green colours, I prefer towards the darker ones:
C2: last column from left to right - mid row;
A3: first column from the left to right - last row down;
B3: second (mid) column from the left to right - last row down.
