Most colours are of artificial origin. Follow the trend of natural colourings. The natural blue colourant Spirulina Blue from algae is a great alternative to artificial colours: the product is heat stable for one hour at 80 °C across a pH range of 3-7.
Spirulina blue acid stable is approved as a colouring agent in Europe and the US and is available in powder and liquid form.
