Frequently asked questions
Is the CMYK value print-accurate?
It's a mathematical conversion. For exact print matching, use your printer's colour profile.
Does it support transparency?
Yes — 8-digit HEX and rgba()/hsla() values keep their alpha.
Is my data uploaded anywhere?
No. Everything runs in your browser with JavaScript — nothing you type or open is sent to our servers.
