The associative perception by a person of a particular colour depends on his/her visual abilities, historical, cultural, religious peculiarities of a region and of course on his/her life experience. Due to this reason a toasted burger cannot be white and a sausage cannot be blue. The same rule applies to vegetarian products.
“Trumix-Ukraine” company has prepared a line of natural food dyes of plant origin for manufacturers of vegetarian products. Using them alone or in combination allows you to get almost any colour.
