Incan white on LEDs?

[kjam22]

I swapped out some of my show to dumbstring pixels and I don't like the "synthetic"white that they produce since it doesn't match my incans, anybody come up with a color code that produces a yellow light closer the incans?

I am using ray's dumb string nodes.

all channels on gives you the led cool white...  start cutting back the blue to remove the "cool" and warm up the color.
how far?  personal preference.
