Am I going color blind? - pool water test

[MrsE88]

Is it just me or do all these shades of yellow look the same?

Hello; Yes the shades seem the same but the transparency is different. Try using a white background with no print which might make differentiation easier. To me the chlorine is between the 0.3 and 0.5 but the print is a bit confusing. I peg PH at 7.6?????

I’ll bring a white recipe card out with me tomorrow and try again. I don’t remember it being this hard to read last year.
The ph is the 7.6

Ok, so the chlorine is low then. I’ve only shocked the pool twice since it’s been set up. I’ll shock it again tomorrow. Last year I messed up and put so much chlorine in that the test turned orange
