HueGrid

Organize color ideas with a focused, offline palette workspace. Create a palette with two to eight colors and edit every color precisely. Enter a six-digit hexadecimal value, adjust hue, saturation, and brightness, or choose from common colors. Each color remains visible as a large swatch, with clear labels for locked and editable states. Explore color relationships when you need direction. Lock the colors you want to preserve, then preview complementary, analogous, triadic, or lightness-step suggestions. Suggestions are based on your selected colors, clearly named, and never replace locked colors automatically. Undo recent palette changes while you explore. Use the contrast checker to choose a text color and background color, preview real sample text, and see the calculated contrast ratio. Select normal or large text guidance, swap foreground and background, and receive neutral feedback such as clear, basic, or weak. The checker is a practical design aid and does not claim universal professional or legal compliance. Save named palettes with notes, color order, lock state, generation rule, and modification time. Search saved work by palette name or color value, mark favorites, copy a one-line color string, or copy a named list for use in another tool. Deleted or changed work remains manageable through the editor and local workflow. Everything is designed for private, offline use. Your palettes and color inputs stay on your device. No account, camera, image access, community feed, advertising, payment, or network connection is needed.
