Floral pigments in Hydrangea are affected by the presence of aluminum ions in the soil, causing changes in flower color from red, pink, blue, light purple or dark purple. [ 4 ] There has been one non-chemical example found within Caesalpinioideae , a single sub-family of Fabaceae where the folding of petals cause changes to the color patterns ...
The red, orange, and yellow wavelengths of light are absorbed so the remaining light seen is composed of green, cyan, and blue wavelengths. This is the main reason the ocean's color is cyan. The relative contribution of reflected skylight and the light scattered back from the depths is strongly dependent on observation angle.
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 ...
White flowers are caused by a recessive allele in tomato plants. They are less desirable in cultivated crops because they have a lower pollination rate. In one study, it was found that chromoplasts are still present in white flowers.
Food plants rich in anthocyanins include the blueberry, raspberry, black rice, and black soybean, among many others that are red, blue, purple, or black. Some of the colors of autumn leaves are derived from anthocyanins. [1] [2]
Fertilizer is often unnecessary at this time of the year because plants doing much growing. 6. Boost Humidity. Low humidity levels and underwatering can both cause plant leaves to turn brown and ...
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]
