Concept:
In colour theory, saturation refers to the purity, vividness, or strength of a colour. The term often associated with this strength is intensity.
A highly saturated colour:
• Appears bright and vivid
• Contains less gray
• Looks pure and strong
A low saturation colour appears dull or faded.
Step 1: Understanding saturation in colour theory.
Colour properties generally include:
• Hue
• Value
• Saturation
Saturation determines how strong or pure a colour appears visually.
Step 2: Analyzing Option (A) Intensity.
Intensity is another term commonly used for colour saturation or colour strength.
A colour with high intensity appears:
• Rich
• Powerful
• Pure
Therefore, this option correctly matches the definition.
Step 3: Analyzing Option (B) Depth.
Depth generally refers to spatial illusion or dimensional appearance, not saturation.
Hence, Option (B) is incorrect.
Step 4: Analyzing Option (C) Brightness.
Brightness refers to lightness or darkness of colour, not its purity or saturation.
Hence, Option (C) is incorrect.
Step 5: Analyzing Option (D) Hues.
Hue refers to the basic colour family such as red, blue, or green.
It does not specifically mean colour strength.
Hence, Option (D) is incorrect.
Final Conclusion:
The saturation or strength of a colour is called:
\[
\boxed{\text{Intensity}}
\]
Therefore, the correct option is:
\[
\boxed{(1)}
\]
