Colour 14700 is also known as FD&C Red No. 4. It is an orange to red colour, but can be blended with other colours to create a wide variety of different hues.
Synthetic colours are regulated and approved for safe use by different governing bodies around the world. In the United States, colours for cosmetics must be specially pre-approved for use by the Food and Drug Administration. Each colour is designated by the letters FD&C (meaning suitable for food, drug and cosmetics), followed by a colour and number designation.
UK-based charity, The Society of Dyers and Colourists has developed an international colour index using the prefix CI before a number.There is a huge array of colour listed under these systems. We use a few of these to supplement our natural pigments, to achieve a full pallet of colour. We find that there are some colours that we cannot achieve using only natural pigments.
Colour adds to the aesthetic of a product and enhances the experience, making the products more fun and exciting. Colour can have a profound effect on our feelings, emotions and wellbeing. For example, it is thought that the colour red makes the heart beat faster.
