Match of Sherwin Williams™ HGSW3221 Subterranean *

Confirm HGSW3221 Subterranean from a physical swatch or a known existing painted sample from the original Sherwin Williams reference. Screen viewing can shift the color, but MyPerfectColor matches the original brand color standard, not an on-screen approximation. Before you order, also confirm the format, sheen, and quantity you need for the item you plan to paint.

For a match of HGSW3221 Subterranean, clean the surface first, remove dust, oils, and grease, and lightly scuff only when the material or existing coating calls for it. Mask nearby areas if needed, and test the paint on the actual surface before coating the full item. Proper prep helps the finished color read more consistently on the part itself.

Plastics vary a lot, so a match of HGSW3221 Subterranean should be tested on the actual plastic before you paint the full part. MyPerfectColor spray paint sticks well to most plastics, and using the MyPerfectColor primer for acrylic enamel can improve adhesion on difficult surfaces. If the plastic is unknown or low-energy, do a test area first so you can confirm adhesion before committing to the whole item.

For HGSW3221 Subterranean in spray form, expect it to be dry to the touch within minutes, ready for recoat in about 1 to 2 hours, and fully cured in about 2 weeks. Dry to touch is only the first stage, so allow more time if the part needs to be handled, assembled, stacked, or put into service.

Custom-made color matches such as HGSW3221 Subterranean should be ordered carefully because made-to-order color products are not returnable or refundable. Before checkout, confirm the exact color reference, the MyPerfectColor format you need, the sheen, and the quantity so the order matches the part you plan to paint.

While MyPerfectColor can provide paint matched to the Sherwin Williams HGSW3221 Subterranean, 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.
