The kelvin endpoint converts a colour temperature in Kelvin into the RGB colour of a black body at that temperature — warm candle and incandescent tones below 3000 K, neutral and daylight whites around 5000–6500 K, and cool bluish light above — using Tanner Helland's well-known approximation, with a plain-English description. The wavelength endpoint converts a wavelength of visible light in nanometres (380–780 nm) into the approximate RGB colour the eye perceives, with the natural intensity fall-off at the edges of the spectrum, and names the band (violet, blue, green, yellow, orange, red). Pure local, no key."
