Step 1: Select Paint Type / Application


A match of Sherwin Williams 42183 reads as a dark, cool blue-green with a muted, gray-cast character. The low LRV gives it a near-ink depth, while the metallic color type suggests a surface that can shift slightly with angle, film build, and sheen.

MyPerfectColor custom spray paint matched to the selected Sherwin Williams 42183 reference can be used on vents, switch covers, speaker grilles, brackets, railings, hardware, small frames, shelving parts, mailboxes, and other removable components where a dark blue-green finish needs to be repeated on mixed materials. It can also work for PVC, access panels, trim pieces, and fixture accents when the item is better sprayed than brushed.

Because the color is dark and subdued, coverage usually reads most evenly on a well-prepared surface. Dark metallic colors can make sanding marks, texture, and sheen differences more visible, and the final appearance may change with substrate color and film thickness. On exterior parts, direct sun can make the blue-green side read a little clearer than it does in shade.
