I think if you've got 2700K elsewhere, 3000K is about as high as you'd want to go inside the cabinets. Anything higher than that is going to be an obvious difference in the rest of what you've got and would look jarring. If you like the 2700 elsewhere, I'd probably just stick with that.

A picture of the room please?

IMO 2700K is already yellow almost like incandescent. I do think too many differnt colors of LED are a mess so if you love 2700 keep it simple and do all the same . BTW my whole home is 4000K i I wanted I gues I could do some dimmers but I love the feel of bright daylight that keeps colors true . The sparkle comes from super clean glassware BTW

@JAN MOYER

Not a lot of glass to worry about ? Too bad those didn't mimic, line up to the lower end doors for more glass.

At any rate? I would make center ART the focus between the glass, light the art instead: ) with a picture light.

Moyer points out that the glass panels are very narrow. Will observers really be able to see what you've stored in the cabinets?

Do you have space between the shelves and the door to install a vertical channel (example) for the LED strips? Are the cabinets wired? Is there space to hide the required power supply?
