Which change is evident when comparing a tint of green with the original green?

Correct answer: The tint will have a lighter value

The governing concept is that a tint is formed by adding white to a colour. Consequently, green becomes lighter in value while remaining within the green hue family; it does not become a primary colour or gain red. Adding white generally reduces saturation rather than increasing it, so option B is also incorrect. Thus option A identifies the visible and defining change.
