Usage note: To see some preset views, click 'view' arrows below the 3D picture.
Each ball and arrow correspond to 1 of 64 Munsell papers measured by Vrhel.
The center of the ball is the paper's stimulus vector under Blackbody5500.
The arrow tip is the stimulus vector under 3 LEDs.
Tristimulus vector of Reference Light (5500K blackbody) = [3.338, 0.3331, 2.178].
Tristimulus vector of LED Light = [3.338, 0.3331, 2.178].
LED amplitudes are adjusted to match the blackbody.
All points are plotted by detailed calculations, no simplifying assumptions.
The spheres are the blackbody locus at a fixed radius from the origin.
