Well, I'm not color blind or so, but I AM having a hellish time trying to guess what shade on the paper is corresponding to the shade of the liquid in the test tube. Most of the time I have to ask my wife (who can paint pictures in oil and so, thus beeing much better on colors than I) and she's having trouble to guess it too.

I wish there were digital electrical any kindamashinethingy to do the testing with. At least a "PH-meter" for FE and NO3.
The hardest testkit of them all is the Hagen PO4 kit. The blue shades of the different levels are so close to eachother that I can hardly tell on the paper, if it is 0 or 0.1. It's a guesswork.

If anyone knows of reasonably priced digital electrical any kindamashinethingy's that can do the job - Please tell me!
If there are not, then this must be a market opportunety for an inventor to exploit.
