<h1 id="color-theory-(study)-s6j71z5vw">Color Theory (Study)</h1>This is a small study on tagging color concepts in the context of artworks that make use of color theory.I'm not an expert on any of these topics, just enjoying learning &amp; sharing.I've also used these as an comparative study on DoRA/LoRA training (I prefer the DoRA results).Usage Guide:These tags are already common Danbooru tags,so applying some of the techniques here to other models might work for more aesthetic color compositions.Color HarmonyExtreme unity leads to under-stimulation,extreme complexity leads to over-stimulation.Harmony is a dynamic equilibrium.Analogous ColorsAnalogous colors are any three colors which are side by side on a 12-part color wheel,such as yellow-green, yellow, and yellow-orange.Usually one of the three colors predominates.Complementary ColorsComplementary colors are any two colors which are directly opposite each other,such as red-green, red-purple and yellow-green.<h2 id="tagging:-yp6m6hc30">Tagging:</h2>For color triggers, theme/background should be interchangeable - but I gave more focus to theme tagging.Color wheel (clockwise order):<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/0ff1d493-299a-4426-bc7e-01cce78fe4e5/width=525/0ff1d493-299a-4426-bc7e-01cce78fe4e5.jpeg" /><pre><code>red theme

cyan,green,yellow

red,purple,blue</code></pre>Selective Coloring:Selective coloring is a photography technique where one color is prominent in the final shot whereas all the other colors have either been changed to monochrome or had their color saturation levels lowered.White:<code>spot color, white theme, white backgroun, light, light beam, dappled light</code>Black:<code>spot color, black theme, dark, shadow</code><hr /><h3 id="license-rdmgienwa">License</h3><a target="_blank" rel="ugc" href="https://freedevproject.org/faipl-1.0-sd/">Fair AI Public License 1.0-SD</a>
