Sugarflair Spectral Food Colouring Paste - Red Satin - 25g Red Satin spectral paste colouring, to colour all your sugarpastes, royal icing, butter icing and cake mixes etc. When mixing into sugarpaste, use sparingly to achieve a pastel shade, but add more to give a strong, vibrant colour - the consistency will not change too much! If used for painting onto sugarpaste, dilute a little with clear spirit or rejuvenator spirit. Water may be used but will not dry as quickly, or give quite such a good finish. Extra concentrated and will darken on drying.
