How is Kelvin accurately converted to sRGB?

The tool uses Tanner Helland's mathematical approximation of the Planckian locus, deriving separate logarithmic curves for R, G, and B below and above 6600K.

What is a Mired (Micro Reciprocal Degree)?

A Mired equals 1,000,000 / Kelvin. It creates a perceptually uniform scale for photographic color correction and optical gel selection.

Why is 6500K the standard for computer displays?

6500K (Illuminant D65) mimics average midday sunlight and is the codified white point for sRGB, Rec.709, and modern digital monitors.

What is Color Temperature in Kelvin?

Color temperature is an objective physical measurement of the hue of a light source, expressed in degrees Kelvin (K). It is based on the radiation emitted by an idealized black-body radiator as it is heated to extreme temperatures.

Contrary to intuitive terms where red feels "hot" and blue feels "cold", in physical color temperature, lower Kelvin ratings (1,800K to 3,000K) emit a warm amber or reddish glow, while higher temperatures (6,500K to 12,000K) produce bright cool white and deep sky blue light.

Color Temperature Spectrum Guide

Kelvin Rating	Light Appearance	Common Real-World Examples	Typical Application
1,800K – 2,200K	Candlelight, Deep Amber	Candles, kerosene lamps, low embers	Cozy dining, mood lighting, fireplace simulation
2,700K – 3,000K	Warm Soft White	Standard incandescent residential bulbs	Living rooms, bedrooms, evening relaxation
3,500K – 4,100K	Neutral White	Office fluorescent fixtures, halogen lamps	Commercial offices, retail storefronts, kitchens
5,000K – 5,500K	Direct Sunlight (D50)	Midday sunshine, electronic camera flashes	Print proofing, graphic design grading, gallery lighting
6,500K	Standard Daylight (D65)	Average noon overcast sky, sRGB display whitepoint	Computer monitors, TV calibration, photography
8,000K – 12,000K	Cool Blue Skylight	Clear northern blue sky in high shade	Architectural exterior lighting, 3D daylight rendering

Frequently Asked Questions (FAQ)

This converter uses Tanner Helland's celebrated mathematical approximation of the Planckian black-body locus. It computes logarithmic equations for Red, Green, and Blue intensities separately for temperatures under 6,600K and above 6,600K, followed by gamma-correction conforming to the standard sRGB color space.

A Mired is calculated as 1,000,000 / Kelvin. Unlike Kelvin, which has non-linear perceptual shifts (a 500K shift at 2,000K is enormous, but barely noticeable at 10,000K), Mireds provide a perceptually uniform scale used extensively by cinematographers and photographers to select color compensation filters (CTO / CTB gels).

6500K (known as Illuminant D65) closely approximates standard Western European daylight at noon. International imaging standards including sRGB, Rec.709, and Adobe RGB established D65 as the reference white point so images and web designs render consistently across diverse hardware.
