RGB

As explained in Deep Learning with Python, Third Edition

A color representation that encodes images using red, green, and blue channels.

RGB represents a color image with three channels: red, green, and blue. It is one way to encode the same visual data that can also be represented in HSV. section 1.4

Choose the representation that fits the task

Selecting all red pixels is simpler in RGB because the representation directly exposes red, green, and blue components. Making an image less saturated is simpler in HSV, which represents hue, saturation, and value. section 1.4

Use RGB as a practical rule of thumb when:

  • The task depends directly on distinguishing red, green, and blue color components. section 1.4
  • You are choosing an input representation that makes the target task easier for a machine learning model. section 1.4

How Deep Learning with Python, Third Edition covers it

How deep it goes
Defines RGB through a task comparison with HSV but stops short of channel-level implementation or encoding details.
Examples
Uses selecting red pixels as an RGB-friendly task and reducing saturation as an HSV-friendly task.
What you can do after
Evaluate whether RGB makes a color-processing task easier than an alternative representation such as HSV.
How it connects
Connects RGB with HSV, data representation, input transformation, and machine learning tasks.
