They are complementary colours which means they bring out the best in each other. They are used together in Colour Therapy to give balance. The balance of cool & warm colours are said to be needed for our wellbeing. Complementary colours are opposite each other on the colour wheel.
Lilacs, violets & purples are known "cool" colours while yellow at the opposite side of the colour wheel is a warm colour. Its the colour of the sun & when teamed with cool colours it balances it with warmth.
