I do not like 2700 K to 3000 K lamps, which are obviously yellowish and regardless how high their CRI may be they distort the colors of clothes or any other objects.
I also do not like the bluish cheap 6500 K lamps.
I consider optimum the 4000 K lamps. This appear white with only a very-slightly yellowish hue, which allows the perception of the natural colors of most objects, but it still provides a warmer sensation than a strictly neutral white color (i.e. one around 5500 K).
