2700k-5000k is fine.
2700k-3500k are warm white.
For local here and specially Chinese, are not so like about warm white. Prefer daylight. That 1 of the cause that lead them into buying the crazy 6500k bright.
Those 6500k are blue white. Since it have some blue, the color render out is not correct.
Example, the red thing you see under this led light is not the actual red. If you take it out under the sun, the red thing is different color.
The measurement for this color rendering is call CRI.
Just to add, there are several youtube videos that demonstrate colour resolution index, e.g. https://youtu.be/O_FsKhhRf_A . Some LCD lamps have the CRI marked on the box.2700k-3500k are warm white.
