Match of James Hardie™ JH40-10 Cobblestone *

If you are repairing chips, scratches, field cuts, rub marks, or service damage on factory-finished siding, choose an Original Material Match option for JH40-10 Cobblestone. That is the touch-up choice because it includes a sheen match.

Other MyPerfectColor formats can still be color-matched to JH40-10 Cobblestone, but they are better for separate parts or broader repainting, not direct touch up on the factory-finished surface.

The color reference is the right starting point, but an aged installed surface can look different because of sun exposure, weathering, chalking, sheen change, texture, and batch variation. A correct JH40-10 Cobblestone match does not guarantee that the repair will blend invisibly beside older material.

If the repair is next to an existing installed section, expect the best result from a careful sample check or site approval rather than relying on the color name alone.

For direct touch up on the factory-finished siding, use an Original Material Match option because it includes a sheen match. If you are painting a replacement part, accessory, or other separate piece that needs to coordinate with JH40-10 Cobblestone, a different MyPerfectColor format may fit that job.

Water-based housepaint and specialty products such as urethane or epoxy can still be color-matched, but they are not the right choice for direct touch up on the original siding surface.

Yes. A match of James Hardie JH40-10 Cobblestone is a James Hardie siding color reference, and MyPerfectColor can make a matched paint for related pieces that need to blend with the siding, such as trim, transition parts, or other adjacent components.

If the job is touch up on the factory-finished surface itself, stay with an Original Material Match option. If the job is a separate part or accessory, choose the product type that fits that part rather than assuming one format works for every application.

Even with the correct JH40-10 Cobblestone color, the repair can read differently if the painted area does not have the same sheen, texture, embossing, or substrate as the original siding. That is why Original Material Match matters for touch up: it adds a sheen match.

If the surface is weathered or textured differently from the factory finish, the color can still be right while the repair remains visible.

It depends. MyPerfectColor matches the color of the James Hardie JH40-10 Cobblestone 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 JH40-10 Cobblestone 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.

MyPerfectColor has the original James Hardie color samples. A sample of the James Hardie JH40-10 Cobblestone you are looking for is in our library. We are able to make paint and verify that it matches the original.

Please note that if your existing materials are not new and you are trying to touch up, they will have aged and are likely different now than they were when new. MyPerfectColor will be sending paint matching the sample at our facility which has not aged the same as your materials and may also be different due to other factors such as variations in manufacturing processes. If your match is critical, you may consider sending a part of your materials for precise color matching. Learn more about our color matching services.
