- Organization: Arrange swatches by hue spectrum or lightness with separated neutral tones
- Swatch Editor: Click to copy hex codes, lock favorite colors, edit or remove swatches, and sample new ones with the eyedropper
- Preview: Compare the image and palette with a side-by-side view, palette-only view, eyedropper loupe, pixel grid overlay, and up to 3200% zoom, with touch panning and pinch-zoom on phones and tablets
- Export: Save as PNG swatches (strip, grid, or preview layout, with optional hex labels), JSON, GPL, CSS variables, or hex lists, or copy to the clipboard
