I like to hear from forum members who have used portable devices to determine which paint matches the color of a given surface.
I notice there are "apps" for smart phones that purportedly do this. e.g. https://www.sherwin-williams.com/homeowners/color/try-on-colors/colorsnap-mobile
Do these require a calibration process? Or are the cameras in phones so standardized that no calibration is needed?
There are also devices that attach to phones.
e.g. https://www.amazon.com/dp/B01KKEMIF0/?tag=pfamazon01-20
Lately, I've needed to find paints to match previously painted concrete block walls. For that purpose, it would be handy to have a something that works off a picture (getting the overall color correct ) rather than something that must be put right on top of a surface.
I'd prefer a standalone device to a smartphone app.
