What color are aged tequilas generally?

Aged tequilas, specifically those labeled as Reposado (aged for a minimum of two months but less than a year) and Añejo (aged for at least one year but less than three years), typically take on a distinct amber or caramel color. This coloration occurs due to the influence of the oak barrels in which the tequila is aged. During aging, compounds from the wood are absorbed into the spirit, imparting color, flavor, and aroma profiles that enhance the overall experience of the tequila. The longer the aging process, the deeper and richer the amber or caramel color tends to become.

In contrast, other colors mentioned in the options are not characteristic of aged tequilas. Cold blue, clear and light, and bright green are not typical hues associated with tequilas that undergo aging, which is why they are not valid choices in this context.
