The yellow and white flowers are newly opened while the magenta flowers are older and have been triggered by pollination to produce more anthocyanins. [1] 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
Generally flowers that are white or green tend to be wind pollinated; where being a bright color isn't necessary. [2] A common phenotype of UV coloration is the “bulls-eye” pattern where a flower reflects UV light at the ends of the petals and absorbs UV light in the center. [4] This acts as a guide for pollinators to locate and find pollen ...
Suntory "blue" rose Rosa 'Cardinal de Richelieu' rose, used for the first genetic engineering experiments. Scientists have yet to produce a truly blue-colored rose; however, after thirteen years of collaborative research by an Australian company, Florigene, and a Japanese company, Suntory, a rose containing the blue pigment delphinidin was created in 2002 by genetic engineering of a white rose ...
In some very economically important flowers like roses, carnations and chrysanthemums despite a lot of efforts was not possible to breed the flowers with blue petals coloration. The lack of F3'5'H enzyme and hence delphinidin type anthocyanin is the reason why blue flower colour was not possible to obtain. [citation needed]
Like all morning glories, the plant entwines itself around structures, growing to a height of 2–3 m (6 ft 7 in – 9 ft 10 in) tall. The leaves are heart-shaped and the stems are covered with brown hairs. The flowers are trumpet-shaped, predominantly blue to purple or white, and 3–6 cm (1.2–2.4 in) in diameter. [5]
Ipomoea indica [3] is a species of flowering plant in the family Convolvulaceae, known by several common names, including blue morning glory, oceanblue morning glory, koali awa, and blue dawn flower. It bears heart-shaped or three-lobed leaves and purple or blue funnel-shaped flowers 6–8 cm (2–3 in) in diameter, from spring to autumn .

An animated sequence of simulated appearances of a red flower (of a zonal geranium) and background foliage under photopic, mesopic, and scotopic conditions. The Purkinje effect or Purkinje phenomenon (Czech: [ˈpurkɪɲɛ] ⓘ; sometimes called the Purkinje shift, often pronounced / p ər ˈ k ɪ n dʒ i /) [1] is the tendency for the peak luminance sensitivity of the eye to shift toward the ...
