	Clerodendrum Trichotomum ''Clerodendrum trichotomum'', the harlequin glorybower, glorytree or peanut butter tree, is a species of flowering plant in the family Lamiaceae. It is native to China, Korea, Taiwan, Japan, India, and the Philippines. It is a large deciduous shrub, growing high. The leaves are ovate, up to long, soft and downy or hairy, producing a peanut odor when crushed. The fragrant flowers are borne on branching peduncles. They have white petals, held within a green calyx which turns red as the fruits ripen. The fruits (drupes) are white, changing to bright blue and eventually dark blue on maturity. They contain the novel blue pigment trichotomine. It is cultivated for its fragrant flowers, autumn colour, and ornamental berries. It is hardy but requires a sheltered position. The variety ''C. trichotomum'' var. ''fargesii'' (Farges' harlequin glorybower) and the cultivar ''C. trichotomum'' var. ''fargesii'' 'Carnival' have gained the Royal Horticultural Society's Award of Garden Merit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Pigment A pigment is a colored material that is completely or nearly insoluble in water. In contrast, dyes are typically soluble, at least at some stage in their use. Generally dyes are often organic compounds whereas pigments are often inorganic compounds. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli. Economic impact In 2006, around 7.4 million tons of inorganic, organic, and special pigments were marketed worldwide. Estimated at around US$14.86 billion in 2018 and will rise at over 4.9% CAGR from 2019 to 2026. The global demand for pigments was roughly US$20.5 billion in 2009. According to an April 2018 report by ''Bloomberg Businessweek'', the estimated value of the pigment industry globally is $30 billion. The value of titanium dioxide – used to enhance the white brightness of many products – was placed at $13.2 billion per year, while the color Ferrari red is valued at $300 million each year.

picture info	Chromophore A chromophore is the part of a molecule responsible for its color. The color that is seen by our eyes is the one not absorbed by the reflecting object within a certain wavelength spectrum of visible light. The chromophore is a region in the molecule where the energy difference between two separate molecular orbitals falls within the range of the visible spectrum. Visible light that hits the chromophore can thus be absorbed by exciting an electron from its ground state into an excited state. In biological molecules that serve to capture or detect light energy, the chromophore is the moiety that causes a conformational change in the molecule when hit by light. Conjugated pi-bond system chromophores Just like how two adjacent p-orbitals in a molecule will form a pi-bond, three or more adjacent p-orbitals in a molecule can form a conjugated pi-system. In a conjugated pi-system, electrons are able to capture certain photons as the electrons resonate along a certain distance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
