Which pigment was used as the primary pigment in the blue rose?

Explanation:
Blue petals come from specific pigments in the pigment family that give blue hues, with delphinidin providing the characteristic blue shade. Delphinidin is a type of anthocyanidin that, when present as blue-leaning pigments in petals (often aided by pH, metal ions, or other co-pigments), produces blue or blue‑purple colors. Carotene yields orange to yellow, and chlorophyll gives green, so they don’t produce blue. Anthocyanin is the broader class of pigments to which delphinidin belongs, but the blue color specifically comes from delphinidin-based compounds.
