I decided to paint this on after realising that my potted hyacinths have flowered into fragrant, tall spikes of dark purple flowers. A purple nail polish was therefore declared to be the winner (I couldnt decide between my hundred bottles. Although I'm pretty sure thats not such a record number for someone who blogs about nail polish, albeit not that often). Does anyone here have more than me? What are your favourite colours?
