Cobalt question

Hi all LC lovers! I recently started buying my adult son Le Creuset. We're thinking a piece or two every birthday and Christmas will have him all set by 30. He loves blue so I picked up a few pieces in Cobalt at the outlet near me. Now we're having trouble finding anything online or in stores in this color. I had originally gone in looking for Marseille. The sales lady told me Marseille was discounted (however that doesn't appear to be correct) so she recommended the Cobalt instead. Is there any chance Cobalt has another name? Or can anyone please tell me what color blue is closest to it? (He prefers a matching kitchen, as opposed to my rainbow collection.) I'm thinking Cobalt is an outlet only color now... Thanks for any help!
