Terms of Service

By using plato·color, you agree to these terms.

The tool is free

This is a free web utility. There is no account, no subscription, no payment. You may use it for personal, commercial, educational, or any lawful purpose.

No warranty

The tool is provided "as is" without warranty of any kind. Color conversion formulas are mathematically standard, but always verify WCAG contrast ratios and color values in your actual design environment before shipping to production.

• CMYK values are computed using the standard RGB→CMYK formula. For press-accurate print matching, use a calibrated ICC profile in professional design software.
• Color blindness simulation uses established Viénot 1999 matrices; real-world perception varies between individuals with the same diagnosis.
• WCAG contrast ratios are computed per the WCAG 2.1 formula. The tool is not a substitute for a certified accessibility audit.
