Warmer lighting is fine for most tasks, if you're having issues with task visibility you probably just need more lights. Most people I see with this issue are relying on a few ceiling lights to do all of the lighting work - minimal ceiling lighting will generally be there to provide ambient light, and should be supplemented with additional lighting for tasks. Lamps in locations where you're reading or writing, pendants or cans in kitchen areas over countertops etc.

I run into this pretty frequently, a customer will have one boob light on the ceiling cranked to 5000k so they can do tasks in the area, when layered, task specific lighting to supplement would make the space a lot more functional without a glaring, cool ceiling light completely dominating the space.

It's all personal preference of course, but I think most people associate overly cool light with hospitals and offices. Really my biggest pet peeve is people who have an assortment of different colors like they just randomly bought whatever bulb was in front of them (which is frequently the case). I can't stand multiple can lights that all have a different color. You can layer in different color lights if it's done with some intention, but man I usually think it looks horrible.
