Lumileds 5500K White LED = Chain of component arrows with cyl radius = 0.03. Stimulus vector = [3.234, 0.1824, 2.347]
Correlated color temperature = 6115.3.
Reference light = JMW daylight = Chain of arrows with cyl radius = 0.02 . Stimulus vector = [3.233, 0.1832, 2.349]
Fattest arrows show the orthonormal components:
Stimulus components in orthonormal system = 3 arrows of radius = 0.04, gray, red, and blue. Stimulus vector = [3.234, 0.1824, 2.347].
The large spheres are the blackbody locus at a fixed radius from the origin.
Starting with the reddest, the temperatures are: [2000, 3000, 4000, 5000, 7000, 1e+004, 2e+004, 1e+005]
