Color & Accessibility
Pick a base color and a harmony rule, and build a five-color palette grounded in color theory. Lock the swatches you like, reshuffle the rest, and copy the whole thing out as ready-to-use CSS variables.
Click a swatch or its hex to copy that color. Lock the ones you want to keep, then hit Shuffle (or press the spacebar) to roll fresh variations of the unlocked swatches around your base.
