Chromatic Color Helper
Bridging colors for everyone.
Free · Designed for iPad. Not verified for macOS.
From “seeing” colors to “communicating” them. Color Helper makes color communication smoother for everyone, including those with color vision deficiencies.
Make colors on iPhone and iPad more accurate and easier to understand.
Newly reimagined!
Chromatic Color Helper is a color-support app that measures colors in front of you and identifies them using official Japanese Industrial Standards (JIS) color names. Extract colors from your camera or photos to find the closest color names along with exact technical values like RGB, CIELAB, and CMYK. From everyday color choices to professional design and education—and to assist color-blind individuals in identifying and sharing colors—bring a "universal language of color" right to your fingertips.
Perfect for When You Want to:
- Instantly share the exact name of a color for food, clothing, or accessories.
- Communicate smoothly with color-blind family members, colleagues, or clients using clear color names.
- Exchange precise color data (values and names) in professional projects.
- Objectively analyze colors for educational or research purposes.
- Assist color communication from a color-blind friendly (accessible) perspective.
