Beetroot is so awesome for coloring! Unfortunately it does not only color the food but also your fingers :D
Turmeric powder is also a good one for coloring food yellow and strangely it does whiten your teeth when used as a toothpaste - nature is full of surprises :)
Yes, nature is full of surprises :)
And the beet colouring, you can wash it off of your hands with some lemon juice ;)
Great advice, I will definitely try that next time ;-)
