A match of Sherwin Williams SW1478 Tranquility is a light, cool blue-green with low chroma and a soft gray cast. It reads more muted than bright, with an airy aqua note that stays restrained rather than saturated.

A match of SW1478 Tranquility in MyPerfectColor custom spray paint works well on small, spray-friendly parts such as HVAC vents, switch plates, outlet covers, speaker grilles, mailboxes, railings, brackets, picture frames, shelving hardware, PVC trim pieces, and fixture accents. It can also be used on baskets, furniture details, and other removable items where a consistent blue-green finish is needed.

Because this is a lighter color, dark or uneven substrates can show through more easily, so surface prep and even film build matter. Finish and texture can shift how much of the blue-green reads versus the gray cast, and glossier applications may make surface flaws or sheen changes more noticeable. If you are coating exterior parts, weather exposure can be harder on muted colors when the substrate or prep is inconsistent.

Frequently Asked Questions About Match of Sherwin Williams™ SW1478 Tranquility *

Will SW1478 Tranquility look the same in matte and gloss if I order a MyPerfectColor match?

The color reference stays SW1478 Tranquility, but the finish can change how it reads after application. Matte, satin, and gloss reflect light differently, so the same matched color can look flatter or deeper depending on sheen.

If you are coating a part that will sit next to an existing painted surface, choose the finish that is closest to that surface. If you are painting the whole item, pick the finish based on the look and wear needs of that item, not just the color code.

How long does MyPerfectColor spray paint in SW1478 Tranquility take to dry, recoat, and handle?

For MyPerfectColor custom spray paint matched to SW1478 Tranquility, it is typically dry to the touch within minutes, can usually be recoated in about 1 to 2 hours, and reaches full cure in about 2 weeks. Those are separate milestones, so dry to the touch does not mean ready for full handling.

If you are coating trim pieces, hardware, vents, or other parts that must be put back in service quickly, plan for the recoat window and the full cure time before heavy use, stacking, or cleaning.

Which finish should I order for SW1478 Tranquility if I am painting fixtures, vents, or hardware?

Choose the finish based on how the item will be used and how you want the surface to perform. Lower sheen finishes usually hide minor surface flaws better, while higher sheen finishes reflect more light and are generally easier to wipe clean.

Because finish changes how SW1478 Tranquility reads, the best choice for a mailbox, vent cover, speaker grille, or similar part is the one that matches the surface around it and fits the cleaning or wear needs of the item. The color match is the same reference, but the finish affects the final appearance.

Can I use SW1478 Tranquility on plastic parts, PVC, or other low-energy surfaces?

MyPerfectColor spray paint matched to SW1478 Tranquility can work on many plastics, but plastic types vary a lot, so testing on the actual part is important. Some plastics also need better prep or a primer to improve adhesion.

For the best chance of success, clean the surface well, follow the prep steps for the specific material, and consider using the MyPerfectColor primer when the substrate is difficult or the part will be handled often. This matters for items like PVC pipe, vents, covers, and similar components.

Where do I find the SDS for SW1478 Tranquility from MyPerfectColor?
