First Claim
1. A method for manufacturing a colour mixture for use in food products, pharmaceuticals and cosmetics with a high light stability, wherein in a first stage a colour, a carrier substance and a solvent as well as eventually further constituents are mixed together to a colour dispersion at a temperature of 20°
- C. to 70°
C., that in a second stage the colour dispersion obtained in the first stage is comminuted by means of industrial dispersing and comminuting instruments such as mills, Turrax homogenizers or stirring instruments to a dispersion with a solid with a mean particle size of less than 30 μ
m in a liquid system, whereby the solid is a carotenoid such as carotene and carotenoids as wells as nature identical as well as of natural origin, a betanin, a riboflavin, an anthocyanine, a carmine product, a curcuminoid, a porphyrene and/or a chlorophyll compound, a chlorophyllin compound, a copper/chlorophyll and/or copper/chlorophyllin compound, that in a third stage a surface active substance is produced at a temperature of 40°
C. to 80°
C. by an aqueous resolution and that in a fourth stage the surface active substance produced in the third stage of the colour dispersion tempered to 30°

Abstract
A colour mixture of higher quality, easy to process and usable in food products, pharmaceuticals and cosmetics made of a colour dispersion and a surface active substance, whereby the dispersion contains the colour in a solid which is for example a carotenoid such as carotene and carotenoids of nature identical as well as natural origin, a betanin, a riboflavin, an anthocyanin, a carmine product, a curcuminoid, a porphyerene and/or a chlorophyll compound, a chlorophyllin compound, a copper/chlorophyll and/or copper/chlorophyllin compound.
