Mired = 1,000,000 / Kelvin
Kelvin = 1,000,000 / Mired
ΔMired = Mired_target – Mired_current
Mired (micro reciprocal degrees) – linear unit for color temperature correction.
Kelvin – absolute color temperature.
Positive ΔMired → warmer (more red/yellow); negative → cooler (more blue).

Understanding White Balance
White balance corrects the color cast caused by different light sources to make whites appear neutral. It is usually adjusted by setting a color temperature (Kelvin) and tint.
Kelvin vs. Mired
Kelvin scale is non‑linear: the visual difference between 2000K and 3000K is much larger than between 6000K and 7000K. Mired (micro reciprocal degrees) linearizes these shifts, making it easier to compare color correction filters and white balance adjustments.

Detailed FAQs
How do I use the RGB multipliers shown in the result?
The RGB multipliers indicate how much to scale each color channel to achieve white balance relative to a 5500K daylight reference. For example, at 3200K (tungsten), R > G > B, meaning you need to reduce red or increase blue. In practice, white balance tools apply these gains automatically.
What is the difference between white balance and color temperature?
Color temperature describes the hue of a light source (e.g., warm yellow, cool blue). White balance is the camera setting that compensates for that color temperature to make white appear neutral. They are two sides of the same concept.
