So today I was in one of the rooms in the gym where they have 4 fluorescent lights shining. 2 of them where clearly low on life/power and they were barely glowing, the glow was this very faint pink color. So my friends asked me why I thought they were glowing pink. On the spot I thought of some random bullshit and said because the lights were obviously very low on power/energy they could only emit light from the shortest wavelength, which is red. I want to know how accurate my hypothesis really is. And if you guys have any ideas as to why the lights had a faint pink glow. I have a newfound interest in science, so little things like this happen to be extremely interesting to me lol.
