What Coastal Blue Actually Looks Like
One color sits in the blue family here: Coastal Blue (#486682, SKU 329207, LRV 12). It's a medium-deep slate or denim blue, cool and moderately saturated rather than bright or pastel. At LRV 12 it's one of the darker colors in the Chalked deck, closer in depth to Farmhouse Red or Rainforest Green than to the lighter blue-greens in the brand's teal family.
That depth is what separates it from the lighter, grayed aqua tones (Blue Harbor, Serenity Blue) grouped under the teal family — Coastal Blue is a true, saturated blue rather than a soft coastal wash.
Painting Furniture With Coastal Blue
Coastal Blue applies directly on bare or painted wood, metal, glass, or ceramic without primer. As a deeper saturated color, a first coat can look uneven before a second thin coat evens out the finish — normal for dark colors in this line, not a defect. Sand back the edges once dry for a worn coastal look, and add a Matte Clear or Protective Topcoat on anything handled regularly, since scuffs show clearly against a deep flat color.
Where Coastal Blue Works
Its denim depth suits headboards, shutters, and accent furniture in coastal or nautical rooms, especially paired with Linen White for a classic navy-and-white look. For a layered blue palette, pair it with Serenity Blue or Blue Harbor from the teal family — the deeper true blue against the lighter grayed aquas reads as intentional rather than mismatched.
Buying, Price, and What's Missing Here
Coastal Blue runs about $20 a quart at Home Depot, Walmart, and Amazon, with a 30 oz can also available — standard Chalked pricing across the deck. It's the only color Rust-Oleum classifies as blue rather than teal; anyone wanting a lighter or more aqua-leaning blue should check the brand's teal family, which holds Blue Harbor and Serenity Blue.
The Questions Everyone Asks
How many blue colors does Rust-Oleum's Chalked line have?
One color classifies as blue: Coastal Blue, at LRV 12, a deep denim-slate tone. The brand's two lighter, grayed aqua colors — Blue Harbor and Serenity Blue — are classified as teal rather than blue, so check that family if you want a softer, lighter option.
Is Coastal Blue a dark or light color?
Dark. At LRV 12 it's one of the deeper colors in the whole Chalked deck, closer to Farmhouse Red or Rainforest Green in depth than to a pastel coastal blue. It reads as a saturated denim or slate blue rather than a soft, airy shade.
How is Coastal Blue different from Blue Harbor or Serenity Blue?
Coastal Blue is a true, deeper saturated blue (LRV 12), while Blue Harbor (LRV 36) and Serenity Blue (LRV 57) are lighter, grayed aqua-teal tones classified separately as teal. If you want a bold navy-adjacent blue, use Coastal Blue; for a softer coastal wash, look at the teal family instead.
Do I need to prime before painting with Coastal Blue?
No — it sticks to bare or already-painted wood, metal, glass, and ceramic without primer. A light scuff-sand only matters over a glossy or waxed finish. As a deep color, plan on two thin coats for full, even coverage rather than one heavy coat.
Where can I buy Coastal Blue and what does it cost?
Home Depot, Walmart, and Amazon carry it in quart and 30 oz sizes, around $20 a quart — the same price as the rest of the Chalked deck. A topcoat isn't bundled with the paint, so add a Matte Clear or Protective Topcoat separately for pieces that see daily use.
