Color Wheel RGB (Additive, Illuminant or Emitting)

Additive, Illuminant, Emitting
In RGB/Additive black is an absence of all colors (there exists no light being emitted, complete darkness).
In RGB/Additive white is a combination of all colors (light wavelengths blend, cast by illuminant sources).
Actual light emitted as if from stage lights, indicate this concept well.
They are scientifically developed for television, monitors, an hand-held screens emitting light.
This concept is harder to grasp as humans rarely combine pure red and green light to create yellow!
