Whether dealing with paint (subtractive) or light (additive), the magic number for primary colours is always three.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
The question asks for the total number of primary colours in standard colour theory.
Step 2: Detailed Explanation
Primary colours are the fundamental colours that cannot be created by mixing other colours. Different colour models have different primaries, but the number is consistently three.
Subtractive Model (RYB): For pigments and paint, the primary colours are Red, Yellow, and Blue.
Additive Model (RGB): For light (screens, monitors), the primary colours are Red, Green, and Blue.
In both major systems, the number of primary colours is 3.
Step 3: Final Answer
There are 3 primary colours.
