Sky spangle definitely. probably just the light but maybe some violet? idk probably just the light. the male looks like a dark green opaline as Airan said. But are his cheek patches lightish in real life? If so, maybe he's a grey green? Another picture might be helpful. They are beautiful though!!
You have a sky blue spangle hen and a grey green opaline male. All female chicks will be opaline. %50 of chicks will be spangle, %50 of the chicks will be grey factored. If your male is split to blue, you can expect greys and grey greens. The color of chicks that aren't greys will vary because we don't know what dark factors he is masking. They're a beautiful pair.
