Colour - Yellow
Yellow is a colour for brave people. It is daring, brash and proudly stands out amongst other colours. The brilliance of yellow can make items in that colour look more dominant, closer than what they really are and can ‘heat’ up an area due to its radiance. It is a colour cherished in cooler climates and celebrated in warm climates.
Tropical gardens tend to be splashed with yellow in the form of flowers and leaves.
More temperate gardens are graced with autumn tones of yellows, browns and reds plus are punctuated in spring with lively yellows in flowering annuals, perennials and bulbs.
Yellow is considered good for memory, concentration, clarity and decision making – ideal for students and intellects. This colour is also great for relief from panic and nervousness.
Too much though in summer can make a garden feel uncomfortable. Care is needed not to overdo this colour in hot climates.
