Question

How many primary colours are there?

• A. 2
• B. 3
• C. 4
• D. 5

Hint:

Remember the acronyms for the two main color models: RYB (Red, Yellow, Blue) for pigments/paint and RGB (Red, Green, Blue) for light. Both systems are based on three primary colors.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Primary colors are the foundational colors from which all other colors can be created through mixing. They themselves cannot be made by mixing other colors. There are two main models for primary colors: the additive model (for light) and the subtractive model (for pigments like paint and ink).

Step 2: Detailed Explanation:
In the context of art and general knowledge, the question typically refers to the subtractive primary colors used in pigments (paint, etc.).
The traditional subtractive primary colors are:

Red
Yellow
Blue
These three colors form the basis of the RYB (Red, Yellow, Blue) color model. By mixing these three colors, secondary colors (like orange, green, and purple) can be created. The other common model is the additive RGB (Red, Green, Blue) model, used for light (e.g., in computer screens and televisions), which also consists of three primary colors. In either standard model, the number of primary colors is three.

Step 3: Final Answer:
There are three primary colors.
