Colorful rose is a kind of rose introduced by a flower company owned by Peter Van de Werken in the Netherlands. Rainbow rose evolved from white rose. The specific cultivation method is to add various edible pigments and dyes into the cultivation water of white roses. After the stem of the white rose absorbed these dyes, it was absorbed by the petals, forming such a delicate rainbow rose. Different from traditional chemical dyes and food plant dyes, "Rainbow Rose" adopts a professional formula for dyeing flowers. Dyes containing special regulating ingredients can prolong the vase life of flowers and improve the freshness of leaves. It is better to use it with the preservative "Flower Saint FLORISSANT600 Gel" which is not available in other products. Hair color is cultivated by mixing anthocyanins, carotene, chlorophyll and other plant pigments. The principle of color development is just like the color matching in painting. We can see that mixing a variety of pigments together is blue. But because its offspring are unstable and cannot be inherited stably, it can only stay in that generation. Although it has been cultivated, it can't be listed in large quantities because it can't be passed down stably. What you see in the market are all other dyed and fake white roses. In a more formal culture, dyeing begins in the growing period of flowers, and the color can be evenly attached to the petals, which looks more natural.
