Even though some flowering plants contain accessory pigments which give them colours they still contain the pigment

Flowering plants primarily contain chlorophyll pigments, which are responsible for their green coloration and essential for photosynthesis. However, some plants also contain accessory pigments such as carotenoids, xanthophylls, and anthocyanins, which give them additional colors such as yellow, orange, and red. So, even though some flowering plants contain these accessory pigments, they still contain chlorophyll pigment. In fact, the presence of these accessory pigments doesn't affect the presence of chlorophyll in plants; instead, they complement and enhance their visual appeal.
