Sharing because some of us may have not discovered this little hack;
When doing water testing (titration, color change hard to see) wear a LED headlamp. Focused, white light makes it so much easier for my old eyes to discern pale pink from pale blue.... (a good white lamp works too, but give the headlamp a try before dismissing this).
Happy almost new year!
