Color meters some of us old farts used or have (something like an Minolta III) isn’t at all useful for digital. A Spectrophotometer can be (depending what kind of geek you are and want to measure). Anything that gives you a value in Kelvin is providing a value within a range, not a specific color.
I didn’t spend too long on the bug site but I don’t see if this is a Colorimeter or a Spectrophotometer (at that price point, I’d hope the later).
