Zen it means of harmony and relaxation; in an interior it not only Asian aspect but harmonious simple design. You can use even the solid colors like black, white or grey – there would be a conformity, nothing non-essential, no overflow accessories and other things. You can also add some Japanese decoration style accessories like candles and flowers. Don’t be scared to create your space in green – that’s the color of nature, a red or scarlet – that would add passion. The subject should be natural and add some plants or flowers – even as a wall art – they would finish the zen look.
