Natural Color Palette of Azaleas
Azaleas are part of the Rhododendron family and are native to various parts of the world, including Asia and North America. The natural color palette of azaleas is a result of the presence of pigments such as anthocyanins and carotenoids in the flowers. Anthocyanins are responsible for the red, purple, and blue colors, while carotenoids produce the yellow and orange hues. The combination and concentration of these pigments determine the final color of the azalea flower.
Red Azaleas
Red azaleas are one of the most striking varieties, with their deep, bold color that can range from a bright fire engine red to a more subdued burgundy.

Pink Azaleas
Pink azaleas are another popular variety, with shades ranging from soft pastel pinks to hot magentas. The pink color is a result of the combination of anthocyanins and carotenoids in the flowers.
