What colour are my two budgies?

Good Morning everyone, 

We recently bought 2 budgies on March 6 2020. I am a first time bird owner and would love to know the colours of them.

My bird Lasagna is Blue with Patterned wings and cute blue spots on his cheeks.

My partner's bird, Sheo is white with a light blue chest and spots on his wings. 

Would anyone also know the age of them? Sheo is smaller than Lasagna.

Thank you very much

One looks to be a normal cobalt, the other a mauve recessive pied.
