Lighting for parameter testing

[tcarter1936]

Hello I'm sorry if this has been covered but I couldn't find it. What lighting should I be using to view test results on my test kits? I mostly use salifert.
Also I need to know more due to my wife having to read the result as I am colorblind and all she does is says it looks like that one lol. I have florescent lights in my kitchen and mostly led elsewhere but some are daylight and some are bright white. Thanks in advance for responses

I like to stand by the window and use natural sunlight when I can. That being said, I've never heard of any particular light source being best for reading the results. Just spit balling here, but I would guess using a consistant light source (same light source each time), would be more important for consistency than whether it's a "warm white" bulb or a "cool white" bulb.
But I'm sure someone will jump in with the best colour temperature light to get the most accurate reading shortly. Tagging along to maybe learn something

I always get the best readings (when compared to lab testing) when I read under cool white fluorescent bulbs. I find warm light especially misleading when reading a test kit that involves pink/red.

I second both posts, in the lighting being cool and consistent.

I would find it most interesting if a red/green colourblind person would test a monochromatic light for such tests. For example a green or red led. (Flashlite)
The colorimeters (Hanna Checker is using green led) is using it so I think it is a chance that at least the titration tests (kH, Ca, Mg) could be possible.

Me to, I actually had a contact lens with a red filter that was prescribed to me and it made things look different but my big issue is I've went 33 years thinking colors looked one way so in respect to the way my brain identifies the color I was still confused. Plus I gave me wicked headaches so I flicked it down the toilette.
I like the idea of the color light I will try it asap.
