Color Blind - Help?!

JessBlount617 · Sunday at 10:08 AM

Hi friends! Happy summer!

I’m helping a friend learn how to test and balance their own water. Husband and wife duo. I take my kit to their house, and the husband says “OHHHH WAIT… I’m colorblind…”

Welp… that wasn’t on my Pool Care Bingo Card. The wife is nervous about testing - which I have reassured her if I can do it anyone can. She doesn’t want to mess it up (we’ve all been there).

So… tell me… are there methods of testing other colorblind friends have used and been successful? Any guidance I can share to my friends is appreciated!

The pH test is probably the hard one for that. But the FC test should be easy to be able to tell if the difference between clear and some kind of pink. Maybe CH and TA would be difficult to find the end point if they can’t see whether the shade changed after adding the final drop.

We have all been there. For there first week or two she could test and make a determination and maybe then share a photo with you for consultation...LOL

There are color matching apps.

You can get a digital pH meter.

Have you gone over the tests to see which ones they can and cannot do?

I think the hubs came up with the perfect excuse for not getting roped into taking care of the pool

A lot of males are red-green color … deficient (rarely are they truly color blind). That really doesn’t make the tests that hard. The pH test looks at shades of red while the FC test (DPD-FAS titration) is a magenta/pink to clear transition. TA is green to red but the transition is fairly sharp. With good enough lighting and a little bit of practice, it should not be that hard. For the pH test, you can always skip the phenol red and just buy a digital pH tester. Apera makes probably the best one on the market for retail customers.

He was so funny!
"Wait... these are all the same color - what do you mean there are different colors" when holding the pH block... his wife and I got a kick out of that - esp. because the pH was WAY beyond 8.2 (super hot pink).

I think the TA test would be the one he struggles with the most - that Green to Red might be the hill he dies on. I can hear him now "IT NEVER CHANGED!!!" as we're cackling in the background because it changed like 27 drops ago...

The FC shouldn't be an issue - if it's bright pink and then NOT then we know we have chlorine. (We did this test - and they had Zero FC in their pool - and judging by the swamp situation, that didn't surprise me).

Can he recognize the difference in traffic lights between red and green lights?
