In the most common type of flame, hydrocarbon flames, the most important factor determining color is oxygen supply and the extent of fuel-oxygen pre-mixing, which determines the rate of combustion and thus the temperature and reaction paths, thereby producing different color hues. Different flame types of a Bunsen burner depend on oxygen supply.
Mallow wildflower. Mauve (/ ˈ m oʊ v / ⓘ, mohv; [2] / ˈ m ɔː v / ⓘ, mawv) is a pale purple color [3] [4] named after the mallow flower (French: mauve).The first use of the word mauve as a color was in 1796–98 according to the Oxford English Dictionary, but its use seems to have been rare before 1859.

On April 3, 2005, an anime series based on My Melody and her friends and produced by Studio Comet started to air on TV Osaka and TV Tokyo television stations, called Onegai My Melody (おねがいマイメロディ), which aired ...
It is advised to check the references for photos of reaction results. [1] Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2]
A comparison between a typical normalized M cone's spectral sensitivity and the CIE 1931 luminosity function for a standard observer in photopic vision.. In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color space).
Rather, every color on the line is a unique mixture in a ratio of fully saturated red and fully saturated violet, the two spectral color endpoints of visibility on the spectrum of pure hues. Colors on the line and spectral colors are the only ones that are fully saturated in the sense that, for any point on the line, no other possible color ...
A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.
