Color & CSS
Pick, convert and test colors for the web — translate between HEX, RGB, HSL and OKLCH, build palettes and gradients, simulate color blindness, check text contrast against WCAG — and generate the CSS that shapes the page: shadows, rounded corners, clip-paths, easing curves and fluid clamp() sizes. Useful for designers matching a brand color and for developers hunting down a CSS value. Previews update live as you adjust each value, and the generators hand you CSS ready to paste.
