Which pigment was the primary one used in making the blue rose?

Explanation:
Blue hues in flowers come from a class of pigments called anthocyanins, and the specific blue tone often comes from delphinidin. Delphinidin-based anthocyanins produce blue to purple colors, while other pigments in the anthocyanin family—like pelargonidin and cyanidin—tend toward orange-red and red-purple tones, respectively. Carotene provides yellows and oranges, and chlorophyll gives greens, so they aren’t responsible for blue. In blue roses, delphinidin is the standout pigment that enables the blue coloration, though factors like pH, co-pigmentation, and metal ions help stabilize and enhance the blue appearance.
