Step 1: Select Paint Type / Application


A match of Sherwin Williams UO12 Storm Cloud reads as a muted blue-gray with a cool cast and low chroma. It is not a bright blue; it leans quiet, slightly slate-like, and sits in a mid-dark range with an LRV of 23.32.

MyPerfectColor custom spray paint matched to the selected Sherwin Williams color reference can be useful for vents, switch covers, speaker grilles, railings, mailboxes, brackets, shelf supports, picture frames, and hardware. The subdued blue-gray character suits parts that need to coordinate with painted surfaces without drawing extra attention.

Because the color is relatively dark, the substrate and finish can change how deep or cool it reads. On lighter or uneven surfaces, coverage and prep matter more, and surface condition may show through the final appearance. For that reason, a careful test application can help confirm even color laydown before finishing the full part.

Frequently Asked Questions About Match of Sherwin Williams™ UO12 Storm Cloud *

How should I confirm UO12 Storm Cloud before ordering a MyPerfectColor match?

Confirm UO12 Storm Cloud from a physical swatch from the original Sherwin Williams color or from a known existing color reference, not from a screen alone. MyPerfectColor matches to the selected brand color reference, so the goal is to verify that UO12 Storm Cloud is the exact target before you place the order.

The code identifies the color target, but it does not tell you the sheen, product line, or how an existing painted surface will look after aging. If you are matching a part that needs to coordinate with another item, make sure the reference you approve is the one you want reproduced.

How much UO12 Storm Cloud spray paint should I order for my project?

Coverage for UO12 Storm Cloud depends on the surface size, texture, hiding power, application method, and how many coats you need. As a general planning guide, a typical can of spray paint covers about 20 square feet with one coat, while other paint formats commonly cover about 400 to 600 square feet.

If the item is textured, porous, dark, or highly visible, plan for extra product because it may take more than one coat to get even coverage. It is also smart to allow for a test spray and any touch-up work on edges, hardware, or complex shapes.

Can UO12 Storm Cloud be used on plastic, and do I need primer?

A match of Sherwin Williams UO12 Storm Cloud can be used on many plastic items, but plastics vary a lot, so test on the actual material before doing the full part. MyPerfectColor spray paint sticks well to most plastics, but using the MyPerfectColor primer can improve adhesion, especially on difficult or low-energy plastics.

For best results, clean the surface well, follow normal prep steps, and make a test application on the same plastic you plan to paint. That is the safest way to confirm adhesion and appearance before committing to the final piece.

What finish should I choose for UO12 Storm Cloud when ordering MyPerfectColor paint?

The right finish for UO12 Storm Cloud depends on how the part will be used and how you want the coated surface to perform. The code identifies the color target, but it does not determine sheen, and sheen can change the way the matched color looks once applied.

In practical terms, glossier finishes are usually easier to wipe clean and can be more durable, while flatter finishes reduce reflection and may hide minor surface imperfections better. Choose the finish that fits the item, its wear level, and the appearance you need after application.

Will UO12 Storm Cloud look the same after I apply it in different lighting conditions?

A match of Sherwin Williams UO12 Storm Cloud can read differently after application depending on lighting, placement, sheen, nearby surfaces, and the substrate under it. That is normal even when the color match itself is correct.

If the part will sit next to an existing painted surface, check the MyPerfectColor match under the same lighting where it will be used and, if possible, on the actual material or a sample panel. That is the best way to judge the final appearance before finishing the full project.
