•
What it is
- •
  an additive color model representing colors through red, greed, and blue components
•
Example
- •
  in an 8-bit-per-channel representation, red cn be $(255, 0, 0)$ and white $(255, 255, 255)$
•
Representation
- •
  three 8-bit channels provide $2^{24}$ possible channel combinations
•
Caution
- •
  channel values require an associated color space and transfer characteristics for precise interpretation
- •
  channel order is a softwrae convention: the supplied OpenCV examples use BGR ordering internally
