Why do HSL and HSV numbers differ?

They model colour cylinders differently — CSS uses HSL while Photoshop-style pickers often expose HSV (brightness vs lightness).

Is CMYK exact for print?

Browser CMYK is an approximation of ISO profiles; always verify with your print vendor's coated or uncoated ICC profile before a press run.

Does 8-digit HEX include alpha?

Yes — the last pair encodes opacity from 00 to FF; not every downstream tool accepts it, so keep an RGBA copy.

Can I paste named colours?

If the tool supports CSS keyword parsing, inputs like `rebeccapurple` resolve to coordinates automatically.

Why did my rounding change slightly?

Floating-point rounding across colour spaces can shift by one unit — acceptable for screen work, not for legal colour specs.

Are inputs sent to a server?

Conversion happens locally in your session.

Paste multiple lines if the UI allows table mode; otherwise convert tokens one at a time for clipboard safety.

What about P3 displays?

Values stay in sRGB unless the tool explicitly supports wide-gamut CSS colour functions — test on hardware if brand colours push vivid extremes.
