Yellow can make small rooms appear larger and brighter, particularly when used in its lighter shades. The darker shades such as gold and honey can be restful and warm. Yellow works well with most colours, particularly cool colours such as blue which balance the warm yellow.

The colour of sunshine, yellow is associated with creative energy, with power and cheerfulness. Bright yellows are stimulating and can be used in large quantities without being too overpowering. It is very good in dark sunless rooms and in hallways since it is so welcoming.
