Navy OC Shirts - Different Shades?

[Blue37]

I recently received four shirts from Officials Choice. Two of them were navy and are different sizes - one to wear behind the plate and one for the bases. The workmanship of the shirts are fine and I like the feel of the fabric, but they are noticeably different in shade. The 2X is so dark as to appear black. The other two shirts are powder blue and are also different sizes, but the shades of those shirts are identical.

Anyone else received an OC shirt that is a darker shade of navy?
