Which color is typically used in drafting to represent a hidden line?

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

Answer: (C)

In drafting, the color commonly used to represent hidden lines is green. Hidden lines are used to illustrate edges, surfaces, or features that are not visible from the current viewpoint of the drawing. The use of a distinct color like green helps differentiate these lines from other types of lines, such as visible edges or centerlines, which might be drawn in black or another color. This visual distinction enhances clarity and makes it easier for anyone reviewing the blueprints to understand which elements are hidden from direct sight. Different drafting standards may utilize various color conventions, but green is widely recognized for hidden lines in many technical drawings, supporting accuracy and efficiency in communication within the design and engineering fields.
