This hobby is really frustrating if you are color blind.

Can you differentiate bright pink from dark purple? If you can, the api one for calcium would probably be a good choice. It goes straight from pink to dark, dark purple-blue and all you have to do is count the drops

I wanted to update this post and say that I have been using the Color Blind Pal app since January and I have been very happy with the results. It is very consistent as long as my lite levels are similar for every test. I test at 11:00 AM and have natural lite coming in and its fine. This has changed my life when it comes to testing so I would give it a try if you are frustrated with the titration test color changes.

Here is what I found to be the best since I am color blind

Alk: Hana Checker
Calc: Salifert with the Color Blind Pal app
Mag: Nyos with the Color Blind Pal app
Nitrate: Nyos (dont need the app, its a yellow change)
Phosphates: Hana Checker

Hope this can help someone out there.
