Is there a way to use a portable device to analyze the color of a surface and determine how to mix a paint color that matches it?
Presumably, a device to analyze the color of surface is a "colorimeter" and such portable devices exist: (e.g. https://www.amazon.com/Portable-Anal...ds=colorimeter ). However, I haven't found any information about using such a device to mix paint colors.
The way I imagine color analyzers in hardware stores working is that they analyze the color in some objective manner and then use a table to convert this analysis to a mixture formula - a certain "base" plut so many "shots" of various pigments. So the way I imagine matching a portable colorimeter working is that you'd measure the color in some physical units and then use a table or algorithm to determine how to formulate the paint mixture - which would probably be different for each different brand of paint (e.g. Behr vs Glliden vs Dunn-Edwards). Is that reasonable?
Edit: I found this: https://www.amazon.com/Color-Muse-co.../dp/B01KKEMIF0 Anyone tried such a device?
