It's all about color temperature. I use 2700K LEDs for anywhere that color rendition matters, like my layout. They give me the warmer incandescent type, and "nostalgic", feel.
In my workshop, and my layout utility lights, I use the higher degree K lights (above 3000K) to give me a bright, almost blue, light for working on the layout.
Pay attention to this and it is easy to get the desired effect you want for different areas of the layout or home.
