Devin's Sketchbook

I'm feeling really sick today so I am foregoing the usual layer management stuff and just winging it. I'm noticing how powerful color temperature contrasts can be by just changing the saturation within one hue. I'm assuming I don't need to change the actual color much because there aren't many different wavelengths of light bouncing around when the only light source in my room is one halogen floor lamp, and outdoors during the day the white light from the sun provides a lot more opportunity for hue shifts to effect color temperature change. I'm still not entirely sure how to marry this stuff with manipulating the color sliders with any degree of confidence, haha. How drastically I change the hue and saturation in these situations (especially from imagination) is mostly just guess work, and I'd love to be able to do that with certainty eventually. I've noticed that things can get muddy when I haphazardly shift hue and saturation without really thinking about things too much (where the reflected light is coming from, the temperature of the main light source, etc).

Example -- something specific I've been trying to get a grasp on from my previous studies, the blue of the sky reflecting off of a warm yellow-orange skin tone shifts the hue towards red-purple and not towards green like paint would do. That's because the colors are mixing optically via an additive process, and not subtractively as if they were pigments? eh? I also have a feeling being color blind is not helping these matters and I cant help but wonder what subtlety I'm not seeing.

Anyway, here's the quick study from tonight. Painting while sick is kind of a drag :durr:
