A match of Sherwin Williams SW6789 Blue Mosque reads as a medium-dark blue-green with a cool, teal-leaning character. It has moderate chroma, so it is clearly colored without looking overly bright or saturated, and the low LRV gives it a deeper, more substantial appearance on finished surfaces.

MyPerfectColor custom spray paint matched to Sherwin Williams SW6789 Blue Mosque can be used on metal vents, speaker grilles, switch plates, brackets, railings, mailboxes, frames, shelving supports, and hardware where a cool blue-green finish is needed. It is also suited to PVC trim pieces, fixture housings, and removable accessories when a repeatable color match matters more than repainting a larger surface.

Because this is a darker color, surface condition and finish can change how it reads. Smooth substrates usually appear cleaner and more even, while textured or porous materials can soften the look slightly. Darker or uneven bases may show through more readily, so prep and film build matter for consistent coverage. Finish choice can also affect perceived depth, with gloss or semi-gloss often making the color feel deeper and more reflective.

Frequently Asked Questions About Match of Sherwin Williams™ SW6789 Blue Mosque *

How do I confirm SW6789 Blue Mosque is the right color before ordering a MyPerfectColor match?

Confirm SW6789 Blue Mosque from a physical swatch, a known existing painted part, or another reliable original brand reference, not from a computer or phone screen alone. Screen color can shift with device settings, lighting, and photography.

MyPerfectColor makes a custom match to the selected brand color reference. It is not the original Sherwin Williams product, so verifying the target color before ordering helps reduce the risk of choosing the wrong color.

Will the finish change how SW6789 Blue Mosque looks after I apply a MyPerfectColor match?

Yes. Finish changes how much light the coating reflects, and that changes how SW6789 Blue Mosque reads on the finished item. A higher-gloss finish will usually look different from a flatter finish even when the color match itself is the same.

If the color needs to sit next to an existing painted surface, try to match the sheen as closely as possible. If the item is new or separate, choose the finish based on the look and wear characteristics you need, then expect the same color to appear a little different in each sheen.

What spray technique works best for SW6789 Blue Mosque MyPerfectColor spray paint?

Use light, even coats and build coverage gradually. Keep the can moving, overlap each pass, and avoid heavy wet passes that can cause runs, uneven sheen, or color build that looks muddy.

For SW6789 Blue Mosque, the final look depends on film build, substrate texture, and how evenly the paint is applied. If the first coat looks thin, let it set and add another light coat rather than trying to cover everything at once.

Which sheen should I choose for SW6789 Blue Mosque when ordering a MyPerfectColor match?

Choose the sheen based on the job, not just the color name. A match of Sherwin Williams SW6789 Blue Mosque can look different in flat, satin, semi-gloss, or gloss because sheen changes reflectivity, cleanup, and how the color appears on the finished part.

If you are matching an existing painted item, the safest choice is usually the sheen that is closest to the surrounding surface. If you are coating a new part, select the finish that fits the handling and durability needs of that item, then order a match of Sherwin Williams SW6789 Blue Mosque in that sheen.

How should I prep metal or an existing coating before spraying SW6789 Blue Mosque?

Clean the surface well, remove grease and contamination, and scuff any sound glossy coating so the new paint can grip. If there is loose rust, peeling paint, or failed coating, remove it before applying a MyPerfectColor match of SW6789 Blue Mosque.

Metal and previously coated parts can vary a lot in texture and condition, and that can change how SW6789 Blue Mosque looks after application. If the existing finish is unknown or in poor shape, test the prep and adhesion on a small area first and use primer when the surface calls for it.
