Exactly like smell and sound, colour has the power to induce a mood with the click of its fingers. It is one of the most important things to help, in strengthening the design of your garden. There is a lot of garden-design theory based around the colour wheel, which of course, is initially an artist’s tool. Colours are arranged in a circle, starting from red at the top through to; red-orange, orange, yellow-orange, yellow, yellow-green, green, blue-green, blue, blue-violet, violet, red-violet and back to red. When you choose a shade that you like on the wheel, you will find harmonious colours on either side. However, if you want to liven up the garden with some mismatched colours, the colour directly opposite, will contrast beautifully with your chosen shade.
