They're right. Chlorophyll is the Only pigment in plant cells.
Pigments in plants color every part: red rose, orange carrot, purple plums. These pigments are not photosynthetic their function varies with location in the plant and the season. Chlorophylls are the primary photosynthetic pigment class found in chloroplasts. Flavonoids like the anthocyanins provide red, blue, purple, or magenta color to flowers and fruits. Color serves to attract pollinators and seed distributors. Recent literature reports some 550 different anthocyanins.
There are carotinoids there too. The yellow, orange and red we see in leaves before they drop. Masked by chlorophyll until that production stops.
