M = 1,000,000/T with T in kelvin; shift = target M − source M, in reciprocal megakelvin (MK⁻¹), commonly called mired. Positive shifts move toward a lower kelvin value (warmer); negative shifts toward a higher kelvin value (cooler). Equal temperatures give zero. Inputs must be positive white-light color temperatures; this arithmetic comparison does not model spectra, Duv/green-magenta offset, color rendering, filter transmission, output losses, LED calibration or camera white balance. No gel product or stack is selected. Compare manufacturer data and verify the real source with a color meter.

Frequently asked questions
Why is the sign important?
3200 K to 5600 K gives −133.928571 MK⁻¹, a cooling shift; reversing them gives the same magnitude with a positive sign. Do not subtract kelvin values or round the intermediate reciprocals.
