A match of Benjamin Moore GX-151 is a dark, cool blue-gray with a low-chroma charcoal cast. It reads more like a deep neutral than a clean blue, and its low LRV of 9.77 puts it in a very dark range.

MyPerfectColor custom spray paint matched to Benjamin Moore GX-151 is useful on small or removable parts where a subdued dark finish is needed, including vents, switch plates, speaker grilles, brackets, railings, mailboxes, shelving hardware, and furniture accents. It can also be used on PVC trim pieces, access covers, and other coated accessories made from metal, plastic, or wood after proper preparation.

Because this color is quite dark, thin coverage or uneven film build can show through on lighter substrates, and surface texture may remain visible after spraying. A smooth, even application helps keep the color reading as a consistent charcoal blue-gray, especially on glossy parts or mixed materials where sheen differences can affect the final appearance.

Frequently Asked Questions About Match of Benjamin Moore™ GX-151 *

Will Benjamin Moore GX-151 look the same in matte and gloss when I order a MyPerfectColor match?

No. A match of Benjamin Moore GX-151 can read differently after application depending on the finish you choose. A matte or low-sheen finish reflects less light, while a gloss finish reflects more light and can make the same matched color appear deeper or slightly different on the finished item.

If you need GX-151 to coordinate with an existing surface, choose the finish first because the final appearance depends on both the color match and the sheen. MyPerfectColor supplies a custom-matched paint to the selected Benjamin Moore color reference, not Benjamin Moore's original paint product.

How much MyPerfectColor GX-151 spray paint should I order for my project?

Plan your GX-151 order around the size of the part, the surface texture, the hiding power of the color, the application method, and how many coats you expect to need. A typical can of spray paint covers about 20 square feet with one coat, but actual coverage can be lower on rough, porous, or dark substrates.

If you are coating a larger item or several parts in GX-151, it is safer to allow extra material for test spraying, touch-ups, and a second coat. Coverage for other MyPerfectColor formats varies by product, so use the package coverage guidance for the specific format you choose.

Can I use MyPerfectColor GX-151 on plastic parts, or do I need special prep?

A match of Benjamin Moore GX-151 can be used on many plastic parts, but plastics vary widely, so the best approach is to test the actual material first. Some plastics accept paint well, while others are low-energy surfaces that may need different prep or primer to improve adhesion.

MyPerfectColor spray paint sticks well to most plastics, and using the MyPerfectColor primer for Acrylic Enamel can improve adhesion when the substrate is difficult. For items like vents, covers, housings, and trim pieces, a small test area is the safest way to confirm how GX-151 will bond and dry on that specific plastic.

How long does MyPerfectColor GX-151 spray paint need to dry before I handle or recoat it?

For GX-151 spray paint, dry to the touch happens within minutes, but that is not the same as being ready for handling or a second coat. Plan on recoating in 1 to 2 hours, and allow about two weeks for full cure before expecting the coating to reach its final handling strength.

If you need to assemble or install the part soon after painting, handle it carefully and treat the first day as a drying period, not a finished cure. Cooler temperatures, heavier coats, and limited airflow can slow the process.

Which finish should I choose when ordering Benjamin Moore GX-151 from MyPerfectColor?

Choose the finish based on how you need GX-151 to perform on the part, not just on how it sounds on paper. Lower sheen finishes usually reduce reflectivity and can make surface texture less noticeable, while higher sheen finishes are more reflective, can be easier to clean, and can make the color read differently after application.

For Benjamin Moore GX-151, order the finish that fits the object you are painting and the look you need once it is installed or handled. MyPerfectColor is providing a custom match to the selected Benjamin Moore color reference, so the sheen you select is part of the final appearance of the finished item.

How do I convert Benjamin Moore GX-151 to a different color from another paint company?

While we can provide Benjamin Moore GX-151 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.
