Scientists create new flower colors through several methods:
- Selective breeding of plants with desired traits
- Genetic modification to activate or suppress color-producing genes
- Manipulation of pH levels and growing conditions
The most common scientific approach is genetic engineering, where researchers can:
- Insert genes from other organisms to produce new pigments
- Modify existing color-producing pathways
- Silence genes that prevent certain color expressions
Famous examples include the development of blue roses and black petunias, which were created by manipulating the anthocyanin production pathways in these flowers.
