Congrats, another nice hatch for you 
The blue keets look like Coral Blues to me tho, my Lite Blues that I've hatched from my flocks have much lighter colors/striping and also have a slight/faint tan tint to their body colors, resembling Lite lavenders. (Could just be how they look in my flocks tho). Any bird can carry hidden recessives that can bring out new colors/shades that aren't in your breeding flock... so any bird carrying the blue gene (not diluted) could have helped produce Coral Blue.
Here's a Coral Blue and lite Blue from my last hatch, you can really see the color difference, especially in the body color. (The Lite Blue keet may be Pied, not sure yet).
