Water test color matching using picture?

[kuramura]

Hi
Just got this idea is it possible to use Photoshop or something similar to match values of color on picture of water sample with test strip???

This is very unscientific, but I tried it out. I used the color dropper to match the 2 colors for each up as best I could so it should be pretty close. I used the center of the sample for the color.

I'm not clear on what you're asking. Do you want to change the color of the water samples in the cups to match a specific color up above on the test strip? Basically, fake a water test?

Sure, that can easily be done. Or am I misunderstanding?

Edit: Looks like we posted at the same time. Now I get it.
