Actually, I think the off colors might have been under-saturated. If I remember correctly, the scope's readout looked kind of like a star, and I think the questionable colors didn't peak out as far as the others. I'm not sure. I've been using more moderate HLS levels for my materials, and rarely go over 180 for lights too. You said don't go over 210 for luminance, and I've been using 210 as my typical cut-off for saturation, with about 235 as my cut-off for luminance. I assume your 210 luminance value applies to white also? It seems difficult to get a "clean" looking white with these lower luminance levels, they appear too gray… I don't have a scope or a high end NTSC monitor. 🙁 Paul S.
