Iron oxide (ferric oxide) is the only red pigment I can think of.
There are also a whole range of synthetic red organic pigments. Toluidine Red is one such example
Two examples include Red Ochre, anhydrous Fe2O3, and the hydrated.
Some examples are carotenoids and phychobiliprotein. Chlorophyll is not an accessory pigment. Accessory pigments are pigments which work alongside Chlorophyll a in photosynthesis, such as carotene.
The color that results from mixing red and yellow pigments is orange.
anthocyanin
The technical names for the pigments in a leaf are carotenoids for orange and yellow pigments, and anthocyanins for red pigments. These pigments play a role in absorbing light for photosynthesis and protecting the plant from damage.
Red
chromoplasts have red and orange carotenoid pigments, that anthocyanins do not have.
antibiotics, pigments
The colors red and yellow combine to make the color orange.
thylacoids contain photosynthetic pigments chlorophylla and β-carote. There are othe pigments (red- phycoenthrin, blue- phycocyan)
You will find chlorophylls and carotenoids, which are the main pigments responsible for capturing light energy in photosynthesis. Chlorophylls are green pigments that absorb blue and red light, while carotenoids are yellow, orange, or red pigments that help broaden the range of light wavelengths that can be absorbed for photosynthesis.
They are carotene and xanthophyll. They are secondary pigments
