A match of Benjamin Moore 2139-10 River Rock is a very dark brown with a restrained olive-yellow undertone. It reads muted rather than clean or saturated, with a low-LRV appearance that gives it an almost shadowed character in paint form.

MyPerfectColor custom spray paint matched to this color can be useful on vents, return grilles, switch plates, speaker grilles, brackets, railings, mailboxes, shutters, metal hardware, and PVC trim pieces when a dark, earthy match is needed on a small or awkward part. It is also a practical choice for removable accessories, display components, shelving ends, and furniture accents that need a consistent dark finish.

Because the color is so dark, substrate color and finish can affect how even it looks after spraying. Light or patchy bases may need more than one coat for full coverage, and glossy finishes can make surface scratches, seams, and texture read more clearly. As with any dark color, film build and sheen can shift the perceived depth once the paint dries.

Frequently Asked Questions About Match of Benjamin Moore™ 2139-10 River Rock *

Can I order 2139-10 River Rock by Benjamin Moore as MyPerfectColor spray paint, and is it Benjamin Moore's original paint?

Yes. MyPerfectColor can make a custom match of 2139-10 River Rock in spray paint and other specialty formats used for color-matching projects. It is MyPerfectColor paint matched to the Benjamin Moore color reference, not Benjamin Moore's original paint product. For Benjamin Moore colors, do not expect interior or exterior house paint options in this collection; choose the format that fits the part you are painting and confirm the sheen separately.

How should I use 2139-10 River Rock as spray paint on baskets, frames, or furniture accents?

For baskets, frames, furniture accents, shelving, and similar items, 2139-10 River Rock is a practical spray-paint match when the goal is to coordinate a smaller object to a known color. Prep the surface so it is clean, dry, and compatible with paint, then apply several light coats instead of one heavy coat. Keep the can moving, overlap passes slightly, and allow proper dry time between coats to reduce runs, uneven sheen, and heavy buildup in corners or weave details.

Why can 2139-10 River Rock look different after MyPerfectColor applies the match?

Even when the match is correct, 2139-10 River Rock can read differently after application because lighting, placement, sheen, surface texture, and nearby materials all affect the finished look. This matters most with a dark color like 2139-10 River Rock, where gloss level and texture can make the same match appear lighter, deeper, or more reflective. Check the finished item in the same conditions where it will be used, not only right after spraying or under shop lighting.

How much 2139-10 River Rock do I need for my project?

Coverage depends on the size of the item, the surface texture, how much hiding is needed, your application method, and how many coats are required. A typical can of spray paint covers about 20 square feet with one coat, but real coverage can be lower on rough, porous, or high-contrast surfaces. Because 2139-10 River Rock is a dark color, plan for enough material to allow light coats and possible follow-up passes if the first coat does not fully hide the surface below.

Which sheen should I choose for 2139-10 River Rock on a metal fixture or accessory?

Choose sheen based on how the part will be used, not just on the color itself. With 2139-10 River Rock, lower sheen finishes usually hide surface irregularities better and reduce reflectivity, while higher sheen finishes can be easier to clean and may make the color read differently in strong light. Since sheen changes the way a matched color looks, pick the finish that fits the object, its wear level, and how closely the new piece needs to coordinate with the surrounding surface.

How quickly will I receive my paint matched to Benjamin Moore 2139-10 River Rock?

Keep in mind that this just shows similar colors based on the color values we have stored in our database. It doesn't mean it is the same or give any approximation about how close the color is. You can play around with the Hue, Lightness and Chroma sliders to expand the selection.
