A match of Sherwin Williams SW1223 Steel Blue is a medium-deep blue-gray with a cool cast and low chroma. It reads as a subdued blue rather than a bright one, with enough gray to soften the color and keep it from feeling overly saturated. Its depth is noticeable, so it tends to show as a grounded, quiet tone rather than a light accent.

MyPerfectColor custom spray paint matched to the selected brand color can be practical on smaller parts and fixtures where a smooth sprayed finish is easier than brushing. It can be used on vents, switch covers, speaker grilles, mailbox hardware, brackets, railings, shutters, PVC trim pieces, cabinet pulls, and other removable or hard-to-reach components that need to coordinate with an existing color reference.

Because this color is moderately dark and relatively low in chroma, substrate color and surface preparation can still affect the final result. Darker or uneven underlayers may show through more readily than they would with a lighter color, and sheen level can make the blue-gray read deeper or flatter. For best evenness, proper prep and enough film build matter, especially on metal, plastic, or previously coated parts.

Frequently Asked Questions About Match of Sherwin Williams™ SW1223 Steel Blue *

Can I order SW1223 Steel Blue as custom spray paint for vents, hardware, railings, or pipe covers?

Yes. A match of Sherwin Williams SW1223 Steel Blue can be ordered as MyPerfectColor custom spray paint matched to that color reference, which is useful for small or awkward items such as vents, grilles, switch covers, hardware, railings, pipes, shutters, and other parts that are easier to spray than brush.

This is a good option when you want the item to coordinate with a known color target and you are painting a removable part or a small surface where spray application is practical. It is MyPerfectColor paint matched to the selected brand color, not the original Sherwin Williams product line.

What should I know before painting plastic parts with SW1223 Steel Blue?

Plastics vary a lot, so a test on the actual part is important before committing to SW1223 Steel Blue. MyPerfectColor spray paint adheres well to most plastics, but prep and adhesion can still change by material type, surface finish, and how the part was molded.

For better adhesion, use the MyPerfectColor primer for Acrylic Enamel before applying the color coat. If the plastic is smooth, flexible, textured, or unknown, test first on an inconspicuous area and confirm that the finish and adhesion are acceptable before painting the full part.

How should I prep metal before applying SW1223 Steel Blue over an existing coating?

Clean the metal first, then scuff the surface so the new coating can bond properly. For SW1223 Steel Blue, existing rust, grease, dust, wax, and other contamination should be removed before spraying, and any loose or failing coating should be addressed before you paint.

The condition of the old coating matters. Gloss, texture, and surface wear can change how the final color reads, even when the color match itself is correct. If the metal has heavy rust or a coating that is peeling, flaking, or unstable, prepare or remove that problem layer before applying the new finish.

How much SW1223 Steel Blue spray paint do I need for my project?

Coverage depends on the size of the item, its texture, how porous or smooth the surface is, how much hiding is needed, and how many coats you plan to apply. A typical can of spray paint covers about 20 square feet with one coat, but real-world coverage can be lower on rough, detailed, or absorbent surfaces.

If you are painting SW1223 Steel Blue on railings, vents, hardware, or multiple small parts, plan for extra material if the surface is textured or if a second coat is likely. For larger projects, estimate by surface area and include test spray and overlap in your calculation.

How do I confirm that SW1223 Steel Blue is the right color before I order?

Confirm SW1223 Steel Blue from a physical swatch from the original brand or from a known existing color reference, not from a screen alone. MyPerfectColor matches to the original brand color standard, so the most important ordering step is making sure the target color reference is the one you actually want.

This matters most when the new paint will sit near an existing surface or when the project depends on repeating a specific legacy color. If the reference is uncertain, verify it before ordering so you do not end up with a correct match to the wrong color target.
