You may be thinking of Xanthophylls. Xanthophylls are the typical yellow pigments of leaves.
There is also an orange pigment, a blue-green pigment, a yellow-green pigment, a gray-brown pigment and a yellow-brown pigment.
Those pigments have different names, such as Carotene (orange), Chlorophyll a (blue-green), Chlorophyll b (yellow-green), Phaeophytin a (gray-brown), and Phaeophytin b (yellow-brown).
xanthophyll
The range of light absorption in leaves is extended by some accessory pigments. But it does not cover the entire visible range.
Carotene gives yellow color to the leaves.
Carotene - an orange pigmentXanthophyll - a yellow pigmentPhaeophytin a[1] - a gray-brown pigmentPhaeophytin b[1] - a yellow-brown pigmentThese are some of the other pigments found in plants other than green pigments.
Plants with non-green leaves have chlorophyll and do carry out the process of PHOTOSYNTHESIS. It is just that the chlorophyll is masked by other pigment.
There are three pigments that are found in a geranium leaf. The three pigments are chlorophyll a, chlorophyll b, and carotenoids.

People cannot perform photosynthesis, in Autumn when tree leaves change colors that is what photosynthesis is. In Autumn, the chlorophyll pigments break down and reveal the presence of accessory pigments.
People cannot photosynthesis... in Autumn when tree leaves turn different colors so that is photosynthesis (In Autumn, the chlorophyll pigments break down and reveal the presence of accessory pigments)
Pigments
Carotene gives yellow color to the leaves.
Leaves get their colors because of the pigments present in them. Red leaves have pigments like anthocyanin.
The leaves are green because of the chlorophyll pigments.
the pigments become visible in the leaves as the seasons change! (A+)
The chlorophyll molecules slowly dies as the temperature slowly lowers. Which causes other colours of the accessory and other pigments to become visible.

The leaves contain no pigments of that color.
