You are a genius Partninja, the use of a pastel shade to paint your Necrons has resulted in something that is refreshing to see and that works really well.
I don't know if it was intentional but what I really like about it is the chalky finish. For me the chalky finish makes the model look old and worn which, considering how old the Necrons are supposed to be, is a brilliant effect.
I also like how the use of the pastel shade makes the model look like it could be made from ceramic or something that is not just metal. Again, a very suitable effect for Necrons.
I am really looking forward to seeing how these turn out and in seeing if you can keep up the chalky finish across all of your models.
