Color snap is easier to navigate, is better at identifying what is/is not a wall, and is much more flexible than SherwinWilliamsColorExpert. The color selection and matching in color snap seems more accurate, will match anything in the photo, and allows to manually select colors in the photo as needed; SherwinWilliamsColorExpert will only color match things it can “identify” and there is not manually adjusting anything. If it can’t identify anything in the photo (e.g. if you use a photo of an empty room without the floor prominently visible) it just gives you an error message and does nothing.
In the photos I tested, it failed to identify features like wood trims/railings/etc, a brick fireplace, and countertops. It not only won’t provide color suggestions based on the wood features, but ‘paints over’ them entirely. It wouldn’t color match the brick fireplace, and would give an error message for most photos where it was visible. It would attempt to identify and color match the countertop, but would then ‘paint over’ large portions of it.
Can’t for the life of me understand why you wouldn’t add what SherwinWilliamsColorExpert is attempting to do as a feature in the existing color snap app instead of launching this as a separate, stand alone app. It’s not a bad idea but I’m not keeping two different Sherwin Williams color selecting/matching apps on my device and color snap is without question the more useful of the two.
