Custom X-Pac Colors Off?

Question about the X-Pac material on the site when customizing a laptop bag. This may just be my monitor but do the blues in the x-pac material seem off? On the site it looks like the Navy is brighter than the OD Blue. But considering the names and the way they look compared to each other, I was wondering if it was a typo or just me. I really want the darker blue in my bag, which to me is navy but the site says OD blue. Just want to make sure since custom bag are not returnable. Thanks
