A hibiscus flower can sometimes have different colored petals on the same bloom due to variations in pH levels within the flower, causing the same anthocyanin pigment to display different colors in different areas, often influenced by genetics and environmental factors like temperature and sunlight, which can affect the pigment's stability; essentially, different parts of the flower can have slightly different chemical conditions, resulting in color variations within a single bloom.
The factors that are responsible for this are:

1) Anthocyanin pigment:
The primary pigment responsible for color variations in hibiscus flowers, particularly reds and blues, is anthocyanin, which can change color depending on the pH level it encounters.

2) pH variations:
Even within a single flower, slight differences in pH can occur, leading to patches of different colors.

3) Genetics:
The specific color variations within a hibiscus flower are primarily determined by the plant's genetics, which influence the types and quantities of pigments produced.

4) Environmental factors:
Temperature, sunlight, and nutrient availability can also slightly affect the color of a hibiscus flower by impacting the production and stability of anthocyanin pigments.
