Question:
What causes the deep rose color of natural roses? And is the cause of color the same for all the deep rose colored natural flowers?


Replies:
The rose color in flowers is from chemical pigments (anthocyanins). The following articles may be of interest. Anthony Brach

"The yellow colors are produced by carotenoids, the reds by anthocyanins, and the modern oranges by a mixture of the two."
