A match of Benjamin Moore GX-104 is a very dark, muted blue-gray with a cool undertone that can read slightly green-blue depending on the finish and substrate. Its low LRV gives it a deep, near-charcoal appearance, while the restrained chroma keeps it quiet rather than vivid.

MyPerfectColor custom spray paint matched to the selected brand color is useful for HVAC vents, switch covers, speaker grilles, metal brackets, handrail parts, mailbox hardware, shutters, and PVC trim pieces where a dark blue-gray finish needs to stay consistent across different materials. It also works well for frames, shelving supports, hardware, and equipment housings that need a restrained, darker color instead of a brighter accent.

Because this is a dark color, surface prep and film build matter. Thin coverage over a lighter substrate can leave contrast showing through, and gloss or semi-gloss finishes may make sanding marks, texture, and edge buildup more noticeable. On small parts placed next to existing painted surfaces, differences in aging, sheen, and surface condition can also be easier to see.

Frequently Asked Questions About Match of Benjamin Moore™ GX-104 *

For Benjamin Moore GX-104, which finish should I choose for a custom-matched MyPerfectColor spray project?

Choose the sheen based on how the part will be used. A higher-sheen finish usually wipes clean more easily and can be a better fit for handled items such as railings, hardware, vents, or fixtures, but it will also show texture and surface flaws more readily. A lower-sheen finish is less reflective and can be more forgiving on rougher surfaces. For Benjamin Moore GX-104, MyPerfectColor is matching the color reference, and the sheen you select changes how that match looks on the finished item.

For this collection, MyPerfectColor offers custom-matched spray paint and other specialty formats rather than Benjamin Moore house paint options.

How do I confirm Benjamin Moore GX-104 before ordering a MyPerfectColor match?

Do not choose GX-104 from a screen alone. Confirm it from a physical Benjamin Moore swatch, an original sample, or a known existing painted part before you order. MyPerfectColor matches to the original brand color reference, so the target should be verified before checkout.

If the part you are copying is faded, dirty, or aged, clean it first and treat it as a reference only if it still represents the color you want. This is the best way to reduce the risk of ordering the wrong match.

What spray technique works best for Benjamin Moore GX-104 on a custom part or fixture?

Use light, even coats and keep the can moving so the finish builds gradually. Overlap each pass slightly and avoid heavy wet passes, since they can cause runs, uneven sheen, or a muddy-looking build that changes how GX-104 reads on the part. Let each coat flash or dry before applying the next coat.

This approach is especially helpful on small or detailed items such as speaker grilles, access covers, brackets, trim pieces, hardware, and removable fixtures where a smooth finish matters more than laying down a thick coat quickly.

What prep is needed if I am coating metal with Benjamin Moore GX-104 over an old finish?

Clean away oil, dust, wax, and any loose contamination before you spray. If the existing coating is glossy and still sound, scuffing it helps the new coating grip better. Remove rust, failing paint, or any flaky material before applying GX-104, since coating over unstable surfaces can affect adhesion and the final look.

For metal fixtures, railings, brackets, pipe, or similar parts, the condition of the old coating can change how the color appears even when the color match is correct. A test area is often the safest way to check the surface before doing the full piece.

What should I check before placing a custom order for Benjamin Moore GX-104?

Before you order GX-104, confirm the color reference, the product format, the sheen, and the quantity. Custom-made color matches are made to order, so the safest approach is to verify the target color from a physical reference and make sure the format fits the item you plan to paint.

For Benjamin Moore GX-104, MyPerfectColor supplies its own matched paint in specialty formats such as custom spray paint and other non-housepaint options. Because these are custom matches, they should be ordered carefully and are not returnable or refundable.

How do I convert Benjamin Moore GX-104 to a different color from another paint company?

While we can provide Benjamin Moore GX-104 in paint, we don't provide any crossover information. We've found that every paint company offers its own unique selection of colors and rarely does a color have an exact equivalent in another brand.

However, under the color image on a color page there is a link that says "Explore Colors". Clicking this link displays colors with similar values and you can look for any colors from the brand you want.

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.
