Are they on the same stem or different stems? If on different stems, there may have been two tiny plants placed in the same pot by the grower. If on the same stem, some plants sport, which means that there is a spontaneous change in the plant’s genetics on that branch that changes some aspect of the plant such as leaf shape or color, or flower size or color. I don’t know how common sports are in azaleas and Rhododendrons.

Since most evergreen azaleas tend to be rather complex hybrids, I would not find it unsual if some of the flowers had a different appearance. And the age of the flower since opening may also have an impact, with older flowers fading to a less intense coloration.

Well they bloomed at same time. What a world.

And what is this bronzing of leaves? Sunburns or lacking something?

Lacebug infestation damaged the leaves. They usually show up in Spring for me so I am not sure if they are still there for you or if they have already left your area. If you see new damage then they are still there. See if you see insects around. Or take pictures every few days and compare leaf damage to see if you detect changes in the leaves or not.
