Is flower dyeing water-based or oily?

The spraying materials for flowers are mostly common water-soluble organic dyes, each with its own color. Flowers are colored by spraying or rhizome absorption, and the coloring method is mostly water-based adsorption coloring, and the coloring time is as long as several hours. After the flowers are colored, the color distribution is uncontrollable and uneven. Most of the flowers are pruned alive and can't be used for potted flowers, so there is a lot of room for improvement.

Flowers are ornamental herbs, which are used to describe the ornamental nature of plants. There are many kinds of short branches with reproductive function.
