Match of Sherwin Williams™ HGSW3321 Blue Midnight *

Confirm HGSW3321 Blue Midnight from a physical Sherwin Williams swatch or a known existing painted reference before you order. MyPerfectColor makes a custom match to the selected brand color reference, not the original brand's paint product, so screen viewing alone is not enough to verify the target.

If you are comparing samples or a painted part, check the reference under the lighting where it will be used and make sure you are matching the intended HGSW3321 Blue Midnight standard, not an aged nearby surface.

The MyPerfectColor match is made to the HGSW3321 Blue Midnight color reference, but the finished look can still change after application. Lighting, sheen, film build, texture, and nearby surfaces can all affect how the color reads on the completed part.

This matters most when the item will sit next to an existing painted surface or when the substrate is different from the original reference. For best planning, judge the color in the actual location and on the actual material whenever possible.

Yes, HGSW3321 Blue Midnight can be ordered as MyPerfectColor custom spray paint for many plastic projects, but plastics vary a lot. Test on the actual plastic part first, since some low-energy surfaces need different prep or primer to get reliable adhesion.

MyPerfectColor spray paint generally sticks well to most plastics, and using the MyPerfectColor primer for acrylic enamel can help improve adhesion when the surface is difficult. For best results, clean the part well and verify the finish on the real material before painting the full item.

Before applying HGSW3321 Blue Midnight, clean the metal or existing coating so oils, dust, and contamination do not interfere with adhesion. If the surface is glossy or slick, a light scuff can help the new coating bond better.

Also check for rust, peeling paint, or other coating failure. The condition of the old surface, plus its gloss and texture, can change the final appearance of the MyPerfectColor match, so repair and prep the surface first if you want the result to read as intended.

Apply HGSW3321 Blue Midnight in light, even coats instead of heavy passes. Keep the can moving, use consistent overlap, and hold a steady spray distance so the color lays down evenly without runs or heavy buildup.

Thin coats also help reduce uneven sheen and muddy-looking coverage. If the item is a difficult shape or a small part, several controlled coats are usually better than trying to cover it in one pass.

Please note that if your material is not new then the paint may not work for touch up as your material has aged and is likely different than it was when new.

If you need a touch up application, send us a part and we can create a touch up solution precisely matching the current color and sheen of your specific materials.

While MyPerfectColor can provide paint matched to the Sherwin Williams HGSW3321 Blue Midnight, we don't provide any crossover information because this is a subjective determination. Every paint company offers its own unique selection of colors and rarely does a color have an exact equivalent in another company's color collection, so determining which color is the best approximation is a judgement call.

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