A match of Behr 1B42-6 Flag Blue is a cool, medium-dark blue with noticeable depth and a slight green bias. It reads as a clean blue rather than a muted navy, and its lower LRV gives it a darker overall presence once applied.

MyPerfectColor custom spray paint matched to the selected brand color can be used on vents, switch covers, speaker grilles, railings, mailbox parts, brackets, hardware, shutters, and other small parts that benefit from a consistent blue finish. It also suits PVC, metal, wood, wicker, and previously coated accessories when proper surface preparation is done.

Because this color is fairly deep and moderately saturated, coverage can vary with substrate and finish. Thin passes over light or uneven bases may show through more readily, and gloss level can shift how blue or green the color appears. On exterior parts, texture and weather exposure can also affect the final reading, so even film build matters.

Frequently Asked Questions About Match of Behr™ 1B42-6 Flag Blue *

Can I order Behr 1B42-6 Flag Blue as a MyPerfectColor custom spray paint match, and what should I confirm before buying?

Yes, but confirm the exact Behr 1B42-6 Flag Blue reference, the MyPerfectColor product type, the sheen, and the quantity before you place the order. A custom-matched paint is made to that selected brand color reference, so the wrong format or finish can lead to the wrong result for your project.

Custom-made color matches are not returnable or refundable, so it is important to verify the order details first. If you need spray paint, make sure you are ordering a MyPerfectColor spray paint match of Behr 1B42-6 Flag Blue and not assuming another product format will behave the same way.

Will MyPerfectColor paint matched to Behr 1B42-6 Flag Blue work on plastic parts, or do I need special prep?

Plastics vary a lot, so it is best to test a match of Behr 1B42-6 Flag Blue on the actual part before finishing the whole item. MyPerfectColor spray paint sticks well to most plastics, but some smooth or low-energy plastics need more prep to get reliable adhesion.

Using the MyPerfectColor primer for Acrylic Enamel can help improve adhesion on difficult plastic surfaces. If the part will be handled often, start with a test piece or an inconspicuous area so you can confirm the prep and finish before coating the full item.

How do I choose the right sheen for Behr 1B42-6 Flag Blue in MyPerfectColor paint?

Choose the sheen based on how the item will be used, cleaned, and viewed. Lower sheens reduce reflectivity, while higher sheens are usually easier to wipe down and will show more shine. The sheen you select can change how a match of Behr 1B42-6 Flag Blue looks on the finished surface.

Do not assume every finish will look the same just because the color reference is the same. If the part is a fixture, panel, hardware piece, or other item that will be handled or cleaned, confirm the finish before ordering so the product choice matches the practical use.

Where can I find the SDS for MyPerfectColor paint matched to Behr 1B42-6 Flag Blue?

The SDS is tied to the specific MyPerfectColor product or chemistry, not to Behr 1B42-6 Flag Blue by itself. If you need the safety information, look up the SDS for the exact MyPerfectColor paint format you plan to order, such as spray paint or another product type.

MyPerfectColor Safety Data Sheets are listed on the Safety Data Sheets page. Check the document for the exact product you are buying so you are reviewing the correct safety information for that match.

If I already chose Behr 1B42-6 Flag Blue, can lighting change how the MyPerfectColor match looks after application?

Yes. Once a match of Behr 1B42-6 Flag Blue is applied, the final appearance can shift with the item's placement, the light source, the sheen, and the nearby surfaces. A color that looked right in one setting can read differently after it is installed or moved.

If the item will sit beside an existing painted surface, judge the match under the same lighting and viewing angle the finished piece will have. That gives you a better expectation of how the color will read in use, especially on fixtures, panels, accessories, or other small parts.
