carotenoid
The scientific term for the orange color in plants is "carotenoids." Carotenoids are a group of pigments responsible for the orange, red, and yellow colors in various plants and fruits. They play a role in photosynthesis and protecting plants from excessive sunlight.
An anthoxanthin is any of a group of water-soluble flavinoid pigments found in plants.

Xanthophylls which are from the carotenoid group of pigments
Chlorophyll absorbs violet-blue and orange-red light spectrum and converts this light energy to chemical energy (photosynthesis). It reflects green and yellow light, causing it to appear to be green. Carotenoids are a group of red, orange, and yellow pigments that work with chlorophyll in the photosynthesis process. Riboflavin, (Vitamin B12), is one of several pale yellow to green pigments that are produced by several plant groups. Flavonoids, found in leaves, block ultraviolet light and admit light that is important to photosynthesis. Flavonoids are important in flower color, providing red and blue pigments. Bright fall colors are produced by the conversion of colorless flavonoids, called flavonols, into colored forms, called anthocyanins. Quinones provide many yellow, red, and orange pigments. Also, xanthophyll and tannin can be found in most trees.
There are many plant based yellow dyes. Some of the more common ones are turmeric, a plant of the ginger family and annato, extracted from the seeds of the achiote tree. Traditional temperate plants for yellow dye include weld, dyers greenweed and goldenrod. Even onion skins can produce yellow under the right conditions.
Chlorophyll (a, b, c, d, e, f), carotenoids (carotenes, xanthophyll, fucoxanthin), and phycobilins (phycoerytherin, phycocyanin) are the major groups of pigments that are associated with photosynthesis. Plants mostly use chlorophyll a, chlorophyll b, carotenes, and xanthophyll as their photosynthetic pigments.
Yes! It is a group of several earthy mineral oxides of iron occurring in yellow, red, brown... ,common use, for pigments.
Methyl orange is red under a pH=3,1 and yellow over a pH=4,4; methyl orange is useful for the titrimetric determination of acids concentration.
In biochemistry, an allophycocyanine is any of a group of accessory pigments to chlorophyll.
Red Orange Yellow Green Blue Indigo Violet
An agrimony is a group of perennial herbaceous plants, genus Agrimonia, with spikes of yellow flowers.
