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).
Accessory pigments such as carotenoids are not usually visible because they absorb light in different regions of the spectrum than chlorophyll. This means they do not contribute significantly to the overall color of the plant. Additionally, chlorophyll is present in much higher concentrations, masking the colors of accessory pigments.
Carotenoids are the pigments responsible for the yellow color of leaves in autumn. These pigments are present in the chloroplasts of plant cells and help in the process of photosynthesis. As the green chlorophyll pigment breaks down in the fall, the carotenoids are revealed, resulting in the yellow hues in leaves.
Plants with non-green leaves like variegated plants still have chlorophyll, but in lower amounts compared to green plants. They can still carry out photosynthesis, although at a slower rate. Variegation is caused by the presence of other pigments in the leaves, which can sometimes mask the green color from chlorophyll.
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.
During the fall season, leaves change color because the green chlorophyll in the leaves breaks down and reveals other pigments, such as reds, oranges, and yellows. This change in pigments makes the leaves appear brighter and more colorful.

Accessory pigments such as carotenoids are not usually visible because they absorb light in different regions of the spectrum than chlorophyll. This means they do not contribute significantly to the overall color of the plant. Additionally, chlorophyll is present in much higher concentrations, masking the colors of accessory pigments.
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.

As the green chlorophyll pigment breaks down in the fall, the carotenoids are revealed, resulting in the yellow hues in leaves.
Leaves turn red due to the presence of pigments called anthocyanins. These pigments are produced in response to environmental stresses like cold temperatures or excess sunlight. They help protect the leaf from damage and also contribute to the vibrant colors seen in autumn foliage.
the pigments become visible in the leaves as the seasons change! (A+)
The leaves are green because of the chlorophyll pigments.
Plants with non-green leaves like variegated plants still have chlorophyll, but in lower amounts compared to green plants. They can still carry out photosynthesis, although at a slower rate. Variegation is caused by the presence of other pigments in the leaves, which can sometimes mask the green color from chlorophyll.
The leaves contain no pigments of that color.
