Is it yellow-ish? I suppose you could call it that.

"Yellow?" tf are you seeing.

I remain convinced people with this take have spent time in chronically underlit environments and haven't actually seen a well-lit space in their lives. If shifting to cool white lets you see better you don't have enough illumination.

@TechConnectify That sounds like you're confusing Kelvin (light colour) with lumens (brightness).

2700K is described as "warm white". Warm usually means towards the red spectrum. So yeah, including yellow.

Everything higher-Kelvin on every source I just found gets cooler, so more blue.

None of that has to do with how "well lit" an area is. That's lumens.

Wtf are *you* seeing?

@eyrea I'm not confusing these at all, but the context wasn't laid out here.

Cool white lines up better with our scotopic night vision. We have more visual acuity in low light levels when the light source is bluer, a la the moon. That's why car headlights and street lighting tend to be so harsh - you need less of it to see the same distances.

In my opinion, if you are feeling as though you need cool white lighting in your home to see well, that means you're using it as a band-aid.
