Carotenoids are organic pigments found in plants that give fruits and vegetables their red, orange, and yellow colors. Phycocyanins are blue pigment proteins found in blue-green algae like spirulina.
Blue corn gets its color from anthocyanins, which are natural pigments that also provide its antioxidant properties. These pigments are responsible for the blue, purple, or black hues found in some fruits and vegetables.
Accessory pigments found in red algae that are good at absorbing blue light are called phycobiliproteins, specifically phycocyanin and allophycocyanin. These pigments help red algae efficiently capture and use blue light for photosynthesis in deep water environments where other wavelengths of light do not penetrate as effectively.
Blue crabs get their color from pigments in their shell, specifically blue carotenoid pigments that are unique to this species. These pigments can reflect blue light, giving the crabs their distinctive blue coloration.
The pigments found in a Mayana leaf are primarily anthocyanins, which are responsible for its purple coloration. Anthocyanins are a type of flavonoid pigment that acts as an antioxidant and gives plants their red, purple, or blue hues.
The pigments found in a vacuole can include anthocyanins (red, purple, or blue), carotenoids (yellow, orange), and chlorophyll (green). These pigments play a role in plant coloration and protection against environmental stress.
Indium is the element that has a shade of blue which is found mostly in indigo. Different elements will have different colors.
Blue paint typically contains pigments like ultramarine, phthalo blue, or cerulean blue. These pigments absorb certain wavelengths of light and reflect blue, giving the paint its blue color.
A blue organelle is typically referred to as a "chromoplast." Chromoplasts are a type of plastid found in plant cells that contain pigments, including carotenoids, which can give them a blue or orange coloration, depending on the specific pigments present. They play a role in photosynthesis and can contribute to the coloration of fruits and flowers, attracting pollinators and seed dispersers. However, it's important to note that blue pigments are less common in plant organelles compared to reds and yellows.
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.
thylacoids contain photosynthetic pigments chlorophylla and β-carote. There are othe pigments (red- phycoenthrin, blue- phycocyan)
