KH and GH don't have colour charts. You add drops till the water in the tube changes colour. GH goes orange at the first drop, then changes to green at the end point, and KH changes from blue to yellow. Count the drops needed to get the colour change, and that's the GH or KH in German degrees. To get ppm, multiply by 17.9.

The pH colour charts can be found here

For pH, test with the mid range one first, then if it measures at the top of that range, use the high pH test. The mid range test uses 3 drops of reagent, the high range test uses 5 drops.
