A match of Sherwin Williams HGSW2371 Long Horizon is a deep, cool blue-green with a muted, low-chroma feel. With an LRV of 8.32, it reads quite dark, and the balance leans more subdued blue than bright green.

MyPerfectColor custom spray paint matched to this Sherwin Williams color reference can be used on vents, switch plates, speaker grilles, railings, brackets, shelf supports, mailbox parts, PVC trim pieces, and small hardware items where a consistent dark blue-green finish is needed on a sprayable surface. It can also suit cabinets, furniture accents, and removable fixture parts when the goal is a darker, quieter color match.

Because the color is dark and relatively restrained, surface prep and finish choice can change the result noticeably. Gloss levels can make it read deeper and can also highlight texture, seams, or sanding marks, while lighter substrates or patchy prep may show through if coverage is uneven. On exterior parts, the muted tone is generally less demanding than a vivid color, but even film build still matters for a uniform result.

Frequently Asked Questions About Match of Sherwin Williams™ HGSW2371 Long Horizon *

Where can I find the SDS for HGSW2371 Long Horizon by Sherwin Williams?

The SDS is tied to the MyPerfectColor product and chemistry, not to the color name alone. If you are ordering a match of HGSW2371 Long Horizon, check the MyPerfectColor Safety Data Sheets for the exact product format you plan to use.

How do I confirm Sherwin Williams HGSW2371 Long Horizon before ordering a MyPerfectColor match?

Confirm HGSW2371 Long Horizon from a physical swatch or another known original-brand color reference, not from a screen image. MyPerfectColor makes a match of HGSW2371 Long Horizon, so it is important to verify the target color before you place the order.

If you are matching an existing painted item, keep in mind that age, wear, sheen, and lighting can change how the color reads on the surface.

Which finish should I choose for a match of HGSW2371 Long Horizon by Sherwin Williams?

Choose the finish based on how the item will be used, cleaned, and viewed. Lower sheen usually hides surface texture better, while higher sheen is easier to wipe down and reflects more light. That means HGSW2371 Long Horizon can look different even when the color match is correct.

If you are coating a small part, removable item, or fixture, MyPerfectColor custom spray paint is often the most practical format. Pick the finish that fits the substrate and the wear the part will see.

Can HGSW2371 Long Horizon be applied to plastic parts?

MyPerfectColor spray paint can adhere well to many plastics, but plastics vary a lot. Test on the actual plastic part first, because slick or low-energy plastics may need different prep or primer to get reliable adhesion.

Using the MyPerfectColor primer can improve adhesion on difficult plastic surfaces. A test piece is the safest way to reduce risk before painting the final part in a match of HGSW2371 Long Horizon.

What prep is needed before spraying HGSW2371 Long Horizon on metal or over an existing coating?

Clean the surface first, then remove rust, dirt, oil, and other contamination. Scuffing the metal or old coating helps the new paint grip better, especially when you are applying a match of HGSW2371 Long Horizon over a glossy or aged finish.

The condition of the existing coating can affect the final result as much as the color match itself. If the old finish is failing, fix that problem first or test in a small area before committing to the full part.
