Single Idea 21185

[filed under theme 27. Natural Reality / B. Modern Physics / 3. Chromodynamics / a. Chromodynamics ]

Full Idea

Colour charge is 'three-dimensional'. As well as the charge having a positive or negative sign, it can also have a direction, and for convenience these three different directions (pointing like a weather vane) are labelled 'red', 'green' and 'blue'.

Gist of Idea

Colour charge is positive or negative, and also has red, green or blue direction
