You can buy LED lamps that will change color to anything you can imagine. Why don't they make a dimmable LED that tracks the color of a dimming incandescent? I could see them starting by taking down the blue and then the green so it would go through yellow to orange and then dim from there to off.
Why do LEDs dim so poorly?

Someone does make LEDs that dim like incandescents. Sorry, I can't recall the name, but they appear at lighting shows. They are not retrofit lamps, but whole fittings. I would guess they're patented and expensive, but I haven't seen the pricing.
Cross-posted sci.engr.lighting - someone there might recall the manufacturer.
Dimming isn't the issue. That's been available for some time (and more/better ones are in the pipe).

The issue was color while dimming.
That's what I was referring to - you can buy LED fittings which dim with the colour temperature shift of indandescents.
Philips has a patent on the color change with dimming. I'll look it up and post the number.
