A match of James Hardie JH70-20 Boothbay Blue is a cool blue-gray with low chroma and a fairly deep value. It reads subdued rather than bright, with the blue softened by noticeable gray so the color stays restrained on large exterior parts.
For direct touch up on factory-finished siding or trim after shipping, installation, field cutting, or service damage, choose Original Material Match because it includes a sheen match. Custom spray paint in this color can also be used on replacement boards, vent covers, shutters, fascia pieces, brackets, fastener caps, and other small accessories that need to coordinate with James Hardie JH70-20 Boothbay Blue.
Because this is a darker, low-chroma color, substrate contrast and surface texture can show through more easily than they would with a lighter finish. A lighter or uneven base may need additional coats for even coverage, and the final look can shift with gloss level, film build, and the condition of the surface being painted.
Aged installed siding can read differently from the color reference because of weathering, chalking, fading, and batch variation. For the closest result on a specific part, compare against the actual piece being painted or an existing protected area, especially when the goal is to blend with installed material rather than coat a separate replacement part.

Yes, if you are doing direct touch up on factory-finished building materials, choose a product option that explicitly says Original Material Match. For James Hardie JH70-20 Boothbay Blue, that is the path that includes a sheen match, which matters for siding touch-up work after shipping damage, installation damage, service work, or field cutting.
MyPerfectColor can make a matched paint for this color reference, but the right product type depends on the job. For touch up on the original surface, use Original Material Match rather than a general color-matched paint format.
A match of James Hardie JH70-20 Boothbay Blue is a factory color reference, so it is the right starting point for a matched paint order. However, an older installed surface can look different because of sun exposure, weathering, chalking, sheen change, texture, and batch variation.
That means the color reference can be correct and the repair can still read differently next to aged siding. If the area is highly visible or the finish has changed over time, an existing part or factory sample is often the safer reference than the nominal color name alone.
For direct touch up on factory-finished building materials, order only a product option that explicitly says Original Material Match, because it includes a sheen match. That is the correct choice for small repairs on siding, trim, or other factory-finished surfaces.
Water-based housepaint and specialty products such as urethane or epoxy can still be color-matched to James Hardie JH70-20 Boothbay Blue, but they do not include a sheen match and should not be treated as direct touch-up products. They are better suited to separate parts, accessories, or broader repainting jobs.
Use James Hardie JH70-20 Boothbay Blue as a building-material color reference when you need paint to coordinate with siding or related exterior components. That can include trim pieces, replacement boards, soffit, fascia, shutters, vents, or other nearby accessories that need to blend with the existing finish.
If the job is direct touch up on the original factory-finished surface, choose an Original Material Match product. If you are painting a replacement part or another accessory, a MyPerfectColor match of this color reference can be the right choice even when the part itself is not the original siding panel.
An existing part or factory sample is the better reference when the installed material has aged, the area is highly visible, or the approval tolerance is tight. In those situations, James Hardie JH70-20 Boothbay Blue may be close, but the actual surface can have different sheen, texture, or weathering than the original reference.
If you can send a sample or match an existing part, that usually reduces the risk of a mismatch on the finished project. This is especially helpful when the repair must blend beside weathered siding or another exposed exterior component.
It depends. MyPerfectColor matches the color of the James Hardie JH70-20 Boothbay Blue but may not match the sheen. If you see Custom Sheen as a sheen option, this means we also match the sheen of the material, otherwise you would need to pick the closest sheen available. However, keep in mind that our version of the James Hardie JH70-20 Boothbay Blue is based on matching an official James Hardie color sample. The color and sheen of your specific James Hardie parts may vary. If your material is not new and has been exposed to the weather, then it is likely that the color has changed over time. MyPerfectColor samples not been exposed to sunlight and weather. If you need a touch up application, you may need to send us a part so we can create a touch up solution precisely matching the current color and sheen of your specific materials.
