Colour your buttercream

Worked out your batch? Concentrated gel colours tint buttercream without thinning it — a cocktail-stick dab goes a long way and the shade deepens as it sits. Liquid colour needs far more and softens the frosting.

Sugarflair Rainbow Gel Food Colours (Set of 6)

Six concentrated gel food colours for buttercream, royal icing, sugarpaste, and cookie painting.

Sugarflair is a UK decorating staple. This six-colour starter set is highly concentrated, so a cocktail-stick dab goes a long way, and the colours deepen as they dry — which is exactly what you want for strong buttercream tones and deep PYO palette colours that still read after a wet brush.

Why we recommend it

The set we would point a new decorator to before they commit to forty individual pots — enough to mix most shades you actually need.

  • Colouring buttercream, royal icing, and sugarpaste
  • Mixing custom shades from a small core set
  • Deep colours for paint-your-own palettes
