Pink is an optimistic colour (expression: "to see everything through rose coloured glasses"). It is purifying as well as coordinating. It remains to fresh flowers. It is tied to innocence, loveliness, and fineness.
We can combine pink with neutral colours such as grey or beige, or even with other colours from the same colour-scheme (maroon, lilac, purple). We can also use it with colours such as blue, yellow and green.
