Gulal is brightly pigmented powder that is thrown at each other by Hindus participating in this Festival each March in Mathura, Northern India that commemorates the playfulness of the love between Krishna and his partner Radha. Bonfires are lit the previous day to drive off evil spirits The mixture of bright colours are meant to symbolise energy, life and joy. The combination of amazing colours and happiness are a fantastic visual inspiration, particularly after recently studying how to make paint from pure pigments.
