struggling to decide the right shade of navy for nursery paint .. overthinking this

I think I'm overthinking the importance for the right shade but I guess I just want it to be perfect . 
Doing a nautical theme and I'm striping one wall to match curtain I bought from pottery barn . 
Not sure if these pics are clear but can anyone tell me which navy matches the curtain the most ? I need a second opinion and my husband doesn't even want to look lol
