If the statute does not involve a suspect or quasi-suspect classification, then rational basis review applies, in which a court must ask whether the statute is rationally-related to a legitimate governmental interest.
Autumn Foliage Color. The Process of Leaf Color Change. Leaves change color during the autumn because the amounts of pigments change as the leaves prepare to fall from the trees. All leaves gradually lose chlorophyll during the growing season, and this loss accelerates before leaf fall.
Foliage: Evergreen leaves are feathery or sometimes scale-like. Leaf color can be silver, green, gold or variegated, and many Callunas change color in the winter, turning brilliant orange, red or chocolate. Several varieties have red, coral or white new growth in spring.
