Colour Mill
Oil-Soluble Food Coloring - Colour Mill Cobalt 100 ml
Oil-soluble food coloring in Cobalt, Pro 100 ml format
Colour Mill Cobalt evokes Delft ceramic pigment and tropical fish scales. This oil-soluble food coloring is designed for fatty pastry bases: melted white chocolate, butter ganache, buttercream, royal icing, and fondant worked with the warmth of your hands. Particularly sought after by cake designers for tropical ocean and diving themed layer cakes and Mediterranean or French Riviera destination wedding cakes, it offers a distinctive shade recognizable from the Colour Mill (Australia) palette.
Made in Australia using proprietary pigment encapsulation technology, Colour Mill withstands baking temperatures of up to 180°C without shifting or fading. The Cobalt shade remains stable after baking, making it the go-to option for colored cake batters before they go into the oven. The 100 ml bottle is designed for boutique bakeries in regular production: at the same volume, it costs approximately 35% less per milliliter than the 20 ml bottle, for everyday use without frequent restocking.

Patissland Tip - Cobalt
Cobalt is brighter and more electric than Royal or Navy; it is the ultimate pop blue. Combine it with Sky Blue and Tiffany for an ocean gradient, or with Yellow and Coral for a summery Côte d’Azur effect. Excellent for children’s ocean-themed birthday parties, sea monsters, and pirates.
Frequently asked questions
At what activity level does the 100 ml size become cost-effective?
The 100 ml size becomes worthwhile from around 5 colored orders per week. To get started or simply test a shade, the 20 ml size (see above) is still more suitable.
How many drops for 250 g of buttercream?
For pastel shades: 2 to 4 drops. For bright shades: 5 to 10 drops. For dark shades: 12 to 20 drops. Always start with less and gradually adjust; it is easier to intensify a color than to lighten it.
Does Colour Mill food coloring withstand baking?
Yes, Colour Mill is one of the few oil-based food colorings that retains its intensity after baking at up to 180°C. This property sets it apart from classic liquid colorings, which become lighter in the oven.
Can Colour Mill be used on water-based mixtures (royal icing, syrup)?
No, Colour Mill oil-based food coloring is designed for fatty bases: melted chocolate, ganache, buttercream, and fondant. For water-based mixtures, use the Colour Mill water-based range.
Does the bottle have a built-in dropper?
Yes, the 100 ml Colour Mill bottle also has a built-in dropper opening in the soft cap, despite the larger container. A simple squeeze dispenses one precise drop.
