A match of Porter Paints 6611-4 Blue Onyx is a muted medium-dark blue with a cool gray cast and a restrained, slightly slate-like character. Its low LRV means it reads fairly deep rather than bright, and the gray influence keeps it from looking overly clean or saturated.

MyPerfectColor custom spray paint matched to the selected brand color can be useful on vents, speaker grilles, switch plates, mailbox parts, brackets, railings, shutters, shelving supports, and hardware pieces where a sprayed finish is easier to control than brushing. It also works well for PVC trim pieces, cabinet accents, and equipment covers when the goal is a coordinated color on a small or removable part.

Because this color is relatively dark and moderately muted, surface preparation and even film build matter. Darker or uneven substrates can affect how many coats are needed, and gloss level can make texture, seams, or repair lines more noticeable. On exterior parts, the color should still read as a subdued blue, but finish and exposure can change how deep or gray it appears.

Frequently Asked Questions About Match of Porter Paints™ 6611-4 Blue Onyx *

How long should I wait before recoating or handling MyPerfectColor spray paint matched to Porter Paints 6611-4 Blue Onyx?

Plan on three different stages: dry to the touch, ready for another coat, and fully cured. For MyPerfectColor spray paint matched to Porter Paints 6611-4 Blue Onyx, the coating is typically dry to the touch in minutes, ready to recoat in about 1 to 2 hours, and fully cured in about 2 weeks.

Do not use dry-to-touch time as the cue for assembly, stacking, or heavy handling. If the part will be installed or put back into service quickly, allow extra time so the coating can harden before use.

How much area will MyPerfectColor spray paint matched to Porter Paints 6611-4 Blue Onyx cover?

Coverage depends on the size of the part, surface texture, how much hiding is needed, the spray method, 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, porous, or highly contrasting surfaces.

For Porter Paints 6611-4 Blue Onyx, plan the quantity around the actual item rather than the color name alone. If you expect two coats or are coating multiple parts, count each coat separately when estimating how many cans you need.

Can I use MyPerfectColor custom spray paint matched to Porter Paints 6611-4 Blue Onyx on baskets, frames, or furniture accents?

Yes. MyPerfectColor custom spray paint matched to Porter Paints 6611-4 Blue Onyx is a practical choice for baskets, frames, shelving, brackets, hardware, decor pieces, and other small items where spray application is easier than brushing.

This is best when the goal is to coordinate a removable or detailed object to a known color reference. Make sure the surface is prepared for the material you are coating, and test the spray pattern on the actual item if the piece has mixed materials or delicate detail.

Will MyPerfectColor spray paint matched to Porter Paints 6611-4 Blue Onyx stick to plastic parts?

Plastics vary widely, so it is important to test on the actual part before committing to the full project. MyPerfectColor spray paint usually sticks well to most plastics, but some low-energy plastics may need extra prep or a primer to improve adhesion.

If the item is plastic, use the MyPerfectColor primer for Acrylic Enamel before applying the color match for Porter Paints 6611-4 Blue Onyx. That is especially helpful when the part is slick, flexible, or will see handling after painting.

Which finish should I choose for MyPerfectColor matched to Porter Paints 6611-4 Blue Onyx?

For Porter Paints 6611-4 Blue Onyx, the sheen matters as much as the color reference because gloss level changes the final appearance. If the painted part needs to coordinate with other coated pieces, match the finish to the application rather than choosing sheen by color name alone.
