Match of Alcoa™ Harbor Grey *

For direct touch up on factory-finished building materials, choose the MyPerfectColor option that explicitly says Original Material Match. That is the format that includes a sheen match, which matters on trim coil, gutters, flashing, and related metal details.

If you choose another product type, it may still be a color match for a separate part or broader repainting job, but it should not be treated as the direct touch-up choice for Alcoa Harbor Grey (75128).

The color reference for Alcoa Harbor Grey (75128) identifies the factory-finish target, but an installed surface can change over time. Sun exposure, weathering, chalking, sheen change, texture, and batch variation can all make the older material read differently beside a fresh match.

That means the reference can be correct and the repair can still stand out next to aged metal. If the adjacent area is weathered or highly visible, the color reference alone may not be the best final judge.

Yes. MyPerfectColor can make matched products for Alcoa Harbor Grey (75128) in different formats, but only the option labeled Original Material Match should be used for direct touch up because it includes a sheen match.

Water-based housepaint, urethane, and epoxy can be color-matched options for other jobs, such as separate parts or broader repainting, but they should not be selected as the direct touch-up product for factory-finished building materials.

Use Alcoa Harbor Grey (75128) as a building-material color reference for related metal parts such as gutters, flashing, trim pieces, and roof details when you need them to coordinate with existing Alcoa trim coil.

If the job is direct touch up on a factory-finished metal piece, select Original Material Match. If you are painting a separate accessory or replacement part, choose the format that fits that part and the application method.

Send an existing part or factory sample when the installed Alcoa Harbor Grey (75128) surface has aged, the finish is high-visibility, or the approval tolerance is tight. That is often safer than matching only the nominal brand color.

An existing part gives MyPerfectColor a real reference for the way the color and finish actually appear in your project. That can help when the current trim coil has weathered or when a close visual match matters more than a catalog reference.

It depends. MyPerfectColor matches the color of the Alcoa Harbor Grey 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 Alcoa Harbor Grey is based on matching an official Alcoa color sample. The color and sheen of your specific Alcoa 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 Alcoa color samples. A sample of the Alcoa Harbor Grey 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.
