Colour Mill Water-Soluble Cobalt Food Coloring
Cobalt shade, 20 ml bottle for water-based mixtures
Colour Mill Water-Soluble Cobalt evokes Delft ceramic pigment and tropical fish scales.

It is a popular choice among cake designers for tropical ocean-themed royal icing cookies and biscuits for Mediterranean destination wedding cakes.

Your questions, our advice
Does the colour hold after the icing has dried completely?
Yes, the shade remains stable once the royal icing has dried completely, after about 24 hours, making it suitable for decorated cookies sold several days after they are made.
How much should I use for a highly saturated shade?
Start with 5 to 10 drops per 250 g of mixture and adjust in increments of 2 to 3 drops until you reach the desired shade, letting it rest between additions.
Does the 20 ml bottle have a dropper?
Yes, the soft bottle cap has a dropper opening: a gentle squeeze dispenses a precise drop.
