Design Studio

Designers and front-end developers constantly need to pick a color, build a palette, craft a gradient, or fine-tune a shadow. Our Design Studio brings these together in one browser-based tool that outputs clean, copy-ready CSS — with nothing uploaded and no account needed.

Pick a color and convert it between HEX, RGB, and HSL; generate harmonious palettes from a base color; design linear gradients with a live preview; and dial in a box-shadow visually. Every result comes with the exact code to paste into your project.

Design Studio

Color picker & converter, palette generator, gradient generator and CSS shadow generator — all running locally in your browser.

100% local — no data ever leaves your browser.

How to use the design studio

  1. 1 Choose a tool from the tabs: Color, Palette, Gradient, or Shadow.
  2. 2 Pick a base color with the picker or by typing a HEX value.
  3. 3 Adjust options — palette type, gradient angle, or shadow offset and blur.
  4. 4 Watch the live preview update as you tweak the controls.
  5. 5 Copy the generated CSS or color values straight into your project.
