Say good buy to synthetic colours ! kids from 2 yrs can safely play with the following and in the light of acute scarcity of water I think this is the best bet 🙂 Boiled mashed beet root for Gulal (pink) and Mint paste for green and Turmeric paste for the yellow ! Turmeric will prevent any cold and infections as it has antiseptic properties if getting wet, green mint will keep u cool and a great cleanser in the hot season, beet root will add natural tint of rouge  such a sweet colour indeed ! What’s more absolutely safe even if these colours are ingested !
Fruit smashes are good too but might get mushy and invite many more creatures to join the holi 🙂
So go ahead and enjoy the herbal holi from this year on !
