Step 1: Select Paint Type / Application


A match of Sherwin Williams 49789 reads as a very dark, cool blue-green with a muted, gray-cast character. The low lightness gives it a near-charcoal depth, while the blue side stays more noticeable than the green side under most lighting.

MyPerfectColor custom spray paint matched to the selected Sherwin Williams 49789 reference can be used on vents, speaker grilles, switch plates, brackets, hardware, railings, mailbox parts, and other removable pieces where a dark blue-green finish needs to carry across metal, plastic, or previously coated surfaces. It can also suit small fixtures, trim pieces, and equipment covers that benefit from a subdued color with a cooler cast.

Because the color is very dark and has a metallic character, surface prep, film build, and finish selection can noticeably change how it reads. Dark colors can make texture, sanding marks, and sheen variation more apparent, and metallics often show substrate differences more readily than flat neutrals. More than one coat may be needed for even coverage, especially over lighter or uneven substrates.
