Solstices are a female-only breed. Originally, all of them had blush-colored/rosy wings, however, newly bred ones have their wing coloration dependent on breeding time: if the egg was laid during the cave's day (between 6am and 6pm), the wings will be blue with a hint of gold, if laid during the cave's night (between 6pm and 6am), the dragon will have that rosy blush on her wings.
