Not enough info but if it helps at all navy blue is a neutral. There isn’t much that doesn’t look good with it; take your pick.. be it lime green , orange, hot pink, gray, yellow... see were I’m going! Anything will be fine except the wrong blue😉

I know it's hard to visualize, and also doesn't photograph well. The whole house is neutral (gray/brown laminate floor, cream white walls, black and gray furniture), so the navy really is the only outlier. It does help to think of blue as a neutral

I'm with Lyn, very little clashes with navy. You could go high contrast with a complementary color in the orange family. You could stick with colors that are adjacent on the color wheel (green and purple). But really, reds, pinks, and yellows all look good with navy. You can go with a bold color (hot pink!) or choose something more muted (terra cotta or a muted olive green). It just depends on where you want to take it.

Thank you Marylee, that visual is great!

Is there a lighter white on the same card as the alabaster? If you want the room to look like the rest of the house, choose a lighter white and the effect would make it look the same. Bringing navy in with soft furnishings would also tie them together. Everyone is right about that navy looks good with many colors.

Do you have any accent colors in the navy room? Or how about elsewhere in your home? I would try to tie in an accent color. If you have Alabaster throughout the house, what color are backsplash, rugs, lamps, bedspread, etc.?

Do you have white moldings throughout your space? You could use that color for the wall. Or try Alabaster at 50% strength, to keep the walls lighter.
