Ipomoea indica flowers change from bright blue to a faded purple by the end of the day. [2] Hibiscus mutabilis flowers changing colors during a day Floral color change occurs in flowers in a wide range of angiosperm taxa that undergo a color change associated with their age, or after successful pollination .
The water in the plants turns green when hit with rays of the sun and the older parts of the plants blacken a little from age. Pseudo-Aristotle, de Coloribus 5.1 [2] However, the shoots and roots which remain underground do not receive sunlight light so instead of turning green they remain white which is the base color of plants before any mixture.
Additionally, the pH of blue cell is around 4,1 and red is lower around 3,3. This supramolecule is relatively unstable and easily can fall apart in result of change of component concentration or pH conditions, so this can explain why blue colour in hydrangea sepals has low stability.

This can happen when an air layer is located just under the epidermis resulting in a white or silvery reflection. [8] It is sometimes called blister variegation. [citation needed] Pilea cadierei (aluminum plant) shows this effect. Leaves of most Cyclamen species show such patterned variegation, varying between plants, but consistent within each ...
In the winter, Valencia oranges reach their optimum orange-rind color while reverting to a green color in the spring and summer. While it was originally thought that chromoplasts were the final stage of plastid development, in 1966 it was proved that chromoplasts can revert to chloroplasts, which causes the oranges to turn back to green.

The brilliant iridescent colors of the peacock's tail feathers are created by structural coloration, as first noted by Isaac Newton and Robert Hooke.. Structural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination ...
Conversely, in Russian and some other languages, there is no single word for blue, but somewhat different words for light blue (голубой, goluboy) and dark blue (синий, siniy). Other color names assigned to bodies of water are sea green and ultramarine blue. Unusual oceanic colorings have given rise to the terms red tide and black tide.
Ocean color is the branch of ocean optics that specifically studies the color of the water and information that can be gained from looking at variations in color. The color of the ocean, while mainly blue, actually varies from blue to green or even yellow, brown or red in some cases. [1]
