A reddish-purple dye is what the Aztecs of ancient Mexico made from the bracts of poinsettias (Euphorbia pulcherrima).Specifically, the bracts are modified leaves. There are two kinds. One are the true bracts that spend their entire lives red in color. They immediately surround the plant's dainty, inconspicuous yellow flower. The transitional bracts are between the true bracts and the plant's regular leaves. The transitional bracts change in color from green to red, in time for the Christmas holidays. The regular leaves always stay green in color.

The transitional bracts are located between the true bracts and the plant's regular leaves. The transitionals start out green in color. But they undergo changes that culminate in their surfaces turning bright red by the time that the flower blooms in December.The red of the true bracts and the reddening of the transitionals may be protective adaptations by which poinsettias protect their flowers.

Can poinsettias be yellow?
Yes, poinsettias (Euphorbia pulcherrima) can be blue.Specifically, this achievement reflects the scientific and technological changes of the 20th and 21st centuries. Among the possibilities that such changes offer is the ability to access a plant's internal structure and affect its biochemistry. For example, red, purple or blue colors are due to the presence of pigments called anthocyanins. Other pigments include the chlorophylls responsible for green colors and the carotenoids responsible for ivory, orange and yellow colors.
