My tip would be to go for lighter coloured sandstone if you can, because the grey colours can look depressing when wet.
But if the patio is in shade then choose greys anyway, because lighter colours look grotty as soon as they get dirty and mossy, so you'll be forever cleaning.
That's my view anyway.
We chose a blue/grey because it complements the the cool colours we use most often in the garden - blues, purples, pinks, creams.
Yellowish colours look better with the warm colours of the spectrum - corals,reds, oranges, dark green, etc
