Frequently asked questions
What color formats can I input?
HEX (#ff0000 or ff0000), RGB (rgb(255,0,0) or 255,0,0), HSL (hsl(0,100%,50%)), CMYK (cmyk(0,100,100,0)), and Tailwind classes (red-500, bg-blue-300).
How does Tailwind matching work?
We match your color to the nearest Tailwind default palette color by Euclidean distance in RGB space. The match is approximate — exact matches show the correct class name.
Is CMYK conversion accurate for print?
CMYK values are calculated mathematically from RGB. For precise print work, use a color-managed ICC profile. Our values are useful for quick reference.
Can I use the color picker?
Yes. Click the color swatch next to the input field to open your system's native color picker. The selected color will update all formats instantly.
