Re: Style and LRGB Emulation in Bicolor

Interesting. That may be the difference. I wonder how it would compare if you composited it the same way but with a synthetic also.
My guess is that the difference in wavelength coverage between what you are using for L and for coloring is causing the result.
I think Ivo has touched on this a number of times here and there (not that I can always understand it, but I'm getting better ), including here above.
Last night I played around with some NB Accent using 2.5 hours of RGB and 8 hours of L-eNhance. Altering things like the luminance and color contribution may well produce an effect that kind of mimics what you might get doing various things in composite such as yay or nay or synthetic or changing the exposure sliders.
Certain of the scheme choices would also give me either a deeper star color or a more yellow and even green, just as you are saying.
But, using the "clean" L, RGB composite like you are, that's more set in stone and no options to change it up. The luminance will not match up well with the color, either in spatial location or intensity. That's my guess anyway.
