A match of Dulux 18 C 40 Deep Space is a very dark blue-gray with a cool cast and low chroma. With an LRV of 4.63, it reads close to charcoal, but the blue undertone keeps it from looking like a flat black.

MyPerfectColor custom spray paint matched to the selected Dulux color can be used on HVAC vents, speaker grilles, switch covers, brackets, railings, mailbox parts, shelving supports, small fixtures, and similar metal or plastic components. The muted depth makes it a practical choice when the part should blend into surrounding hardware rather than draw attention.

Because the color is so dark, surface condition, film build, and sheen can change how it reads. Thin areas may show substrate contrast more quickly, and glossier finishes can make texture or prep marks more noticeable, so even application and good preparation matter. On plastic, metal, or previously coated parts, adhesion and final depth can vary with the surface and finish selected.
