Ph test

I'm thinking the same thing...I would say they just change the dye to give a different color but also I don't have the color match card to know where I'm at. Not worth the gamble
 
The colors are so bad/similar it really only tells you if you are above or below 8 which isnt terrible but its also not that useful if you are trying to maintain a stable pH.
