Question

Which is the opposite colour of yellow colour?

• A. Green
• B. White
• C. Black
• D. Blue

Hint:

Remember the main complementary pairs: In the artist's RYB wheel, they are Red-Green, Yellow-Purple, and Blue-Orange. In the RGB light model, they are Red-Cyan, Green-Magenta, and Blue-Yellow. Exam questions often use the modern models.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
The term "opposite colour" in art and colour theory typically refers to the complementary colour. Complementary colours are pairs of colours which, when combined or mixed, cancel each other out (lose hue) by producing a grayscale colour like white or black. When placed next to each other, they create the strongest contrast for those two colours.
Step 2: Detailed Explanation
The complementary pair for yellow depends on the colour model being used:
RYB (Subtractive) Model: Used by artists for pigments. The opposite of Yellow is Purple (Violet).
RGB (Additive) Model: Used for light (e.g., screens). Yellow light is a mix of Red and Green light. Its opposite is Blue light, because Yellow (R+G) + Blue = White light.
CMYK (Subtractive) Model: Used for printing. The opposite of Yellow is effectively Blue.
Since Purple/Violet is not an option, the question is referring to the modern RGB or CMYK models where the opposite of yellow is blue.
Step 3: Final Answer
Given the options, Blue is the correct opposite/complementary colour to Yellow.
