APi high range PH test kit

I have a brand new kit. However the Coker in the test tube is none of the colors on the color card. Thinking I may have had a bad kit I went and bought another of a different lot. Nope! Same problem. My test water is pink and the card shows yellow, brown, and purple. I'm afraid I don't reccomend this kit as being very accurate.
