I enjoy this color generator because of how it generates a palette with lights and darks of the colors, the "palette type" icons, and the ability to finely tune colors with degrees of hue, secondary color distance, and even more fine tuning tools.
Also, exports as HTML, CSS, LESS, SASS, XML, and Text...also with color contrast tables, color swatches, examples.
It's a one-page-punch with holistic color tooling.
