You can pick a color from your screen in browsers that support the EyeDropper API.
Take a printed CMYK reference and bring it into a CSS-friendly HSL form so you can fine-tune hue or lightness in a stylesheet. The tool runs CMYK through sRGB before computing HSL, which means the same gamut caveats apply as with any direct CMYK to web conversion.
After conversion, try nudging lightness in 5 percent steps to build accessible variants of the brand color without losing the original hue identity.
Need more notations? Open the Color Converter for HEX, RGB, HSL, LAB, OKLAB, and OKLCH, or use the Color Contrast Checker to validate foreground/background pairs before shipping.
