A flower’s size, shape, color, scent, and pattern all play a role in signaling with the senses of pollinators. [2] Plants that rely on animal pollinators are most likely to use the UV coloration strategy compared to other plants to increase the odds of them being pollinated. [7]
Color photography (also spelled as colour photography in Commonwealth English) is photography that uses media capable of capturing and reproducing colors.

In photography (particularly digital photography), purple fringing (sometimes called PF) is the term for an unfocused purple or magenta "ghost" image on a photograph.This optical aberration is generally most visible as a coloring and lightening of dark edges adjacent to bright areas of broad-spectrum illumination, such as daylight or various types of gas-discharge lamps.
The cyanotype was discovered, [2] and named thus, by Sir John Herschel who in 1842 published his investigation of light on iron compounds, [3] expecting that photochemical reactions would reveal, in form visible to the human eye, the infrared extreme of the electromagnetic spectrum detected by his father William Herschel and the ultra-violet or 'actinic' rays that had been discovered in 1801 ...

The first hand-coloured daguerreotypes are attributed to Swiss painter and printmaker Johann Baptist Isenring , who used a mixture of gum arabic and pigments to colour daguerreotypes soon after their invention in 1839.
