What's the difference between warm yellow light, warm white light and white light? How to distinguish them?

Warm yellow is warmer, white light is white, and warm white light belongs to both. Different color temperatures of light sources bring different feelings. The light color from 2700K to 3200K is yellow, the light color from 3200K to 5000K is warm white, and the light color from 5000K to 6500K is called white light. In fact, you can see it just by lighting it.
