Not sure I can call this a SHO palette so I put that odd designation in the title. By [H]S-ShO-O I mean the Luminance is all Ha, the Red is SII, the Green is a mix of 47.5% SII + 5% Ha + 47.5% OIII, and the Blue is OIII.

I liked how the SII/OIII bi-color looked but I wanted to get the additional color and structure separation of having all three channels represented in color. So I added just a touch of Ha. Is this how you would do it? What would your method be? Still learning here...

Color balance shift. Didn't look the same once I uploaded to Astrobin.
