Step 1: Select Paint Type / Application


A match of Sherwin Williams SW6740 Kilkenny is a medium-deep green with a cool, slightly blue-leaning undertone. It reads more grounded than bright, with moderate chroma and an LRV of 18.69 that keeps it on the darker side without turning into a near-black green.

MyPerfectColor custom spray paint matched to the selected brand color can be useful for exterior and utility parts where a defined green finish is needed. It can work on railings, shutters, mailbox hardware, vent covers, speaker grilles, PVC trim, brackets, frames, shelving, and small fixtures that are easier to spray than brush, especially when you want a consistent finish on metal, plastic, wood, or previously coated pieces after proper prep.

Because this is a deeper color, surface preparation and finish choice can change the result more noticeably than they do with lighter colors. Scratches, sanding marks, or texture can show through more readily in smoother sheens, and lighter or uneven substrates may need better coverage to keep the color reading even. Finish and film build will also affect how dark and saturated it appears once dry.

Frequently Asked Questions About Match of Sherwin Williams™ SW6740 Kilkenny *

Can I order Sherwin Williams SW6740 Kilkenny in MyPerfectColor custom spray paint for trim, vents, or hardware?

Yes. MyPerfectColor can make a custom spray paint match of Sherwin Williams SW6740 Kilkenny for small parts and awkward shapes such as trim details, vents, railings, pipes, grilles, switch covers, hardware, and similar items. It is a practical choice when brushing would be difficult or when you need a removable part to coordinate with a painted surface.

If the item is large or heavily exposed, check whether spray application is the right format before ordering, since coverage method and surface prep can matter as much as the color match.

How long does Sherwin Williams SW6740 Kilkenny spray paint take to dry, recoat, and handle?

For MyPerfectColor custom spray paint matched to Sherwin Williams SW6740 Kilkenny, dry-to-touch is usually within minutes, recoating is typically done in 1 to 2 hours, and full cure is about two weeks. These are different stages, so a coat that feels dry may still need more time before heavy handling or assembly.

If the part will be reassembled, stacked, or installed right away, plan around the full cure time rather than only the dry-to-touch time.

Can Sherwin Williams SW6740 Kilkenny be used on plastic or other difficult surfaces?

Yes, but plastics vary widely, so test Sherwin Williams SW6740 Kilkenny on the actual plastic before doing the full job. MyPerfectColor spray paint adheres well to most plastics, but some low-energy surfaces need extra prep or a primer to improve bonding.

For better adhesion, use the MyPerfectColor primer for Acrylic Enamel and follow it with a test spray on the real substrate. That is the safest way to reduce surprises on PVC, molded parts, or other difficult plastics.

Which sheen should I choose for Sherwin Williams SW6740 Kilkenny?

The right sheen for Sherwin Williams SW6740 Kilkenny depends on how the part will be used, not just the color reference. Lower sheen finishes generally hide surface imperfections better and reduce reflectivity, while higher sheen finishes are easier to wipe down and can look brighter on the finished item.

Keep in mind that the same matched color can look different across sheen levels. If you are trying to coordinate a new piece with an existing painted surface, the sheen choice can matter as much as the color match itself.
