Food Colouring?

Is food colouring to be used among bibekis? My kids are often asking me for coloured foods much like their friends at school, like coloured icing and coloured sprinkles but I only know how to make these either white or brown (from cacao powder). Is it ok to use? If so, which is more suitable/acceptable - powdered or liquid food colouring?

What about maple syrup and hot sauce? I know of several sarbloh bibekis that use both in cooking but have always been skeptical to use it myself without asking more bibekis about their thoughts on it first...

What does sangat on this forum think about it?

Bhenji you might want to try one of the following...

Yellow: boil 50mL water with one teaspoon of turmeric for 5 min. Then let it cool down and add one teaspoon to icing.

Green: boil 1 cup of fresh spinach for 5 min, drain, blend spinach with water (2-4 table spoons), strain, cool, add to icing.

Purple: Blend blueberries with small amount of water, strain, add to icing.
