The number is only a starting point
2700K generally appears warmer than 3000K. Neither is a promise that a room will feel welcoming. Materials, brightness and the distribution of light change the result. Colour temperature also does not tell you how faithfully a source renders colours.
I prefer to compare samples against the actual finishes. Timber, paint, stone and skin are more useful references than a photograph of a shop wall.
Match the experience across the room
Fittings with the same stated temperature can still look different. I look at the selected lights together and at the levels people will use. A small mismatch becomes more obvious when two sources wash the same surface.
Dim-to-warm changes colour as the light level drops. That can suit a relaxed evening setting, but the range and behaviour depend on the product. It is worth seeing the whole dimming journey.
Let the task and atmosphere decide
I might want a kitchen to feel clear for preparation and softer when the work is finished. Separate layers can do that without asking every light to change colour.
The decision should be made in context. Test the sample after dark, dim it and look at it beside the other sources before specifying the room.
