ColorCard Pro by Camera Butter
Accurate color reference cards
Free
A precise calibration and color-grading tool for filmmakers — a reliable color checker and white balance card for matching footage across any camera.
Bring studio-grade color accuracy to your pocket.
ColorCard Pro by Camera Butter turns your iPhone or iPad into a precisely calibrated grey and color reference card — tuned to your specific device’s display profile for unmatched consistency in the field and in post-production.
No more guessing exposure or color balance. Whether you’re shooting outdoors with an action camera or color-grading footage in DaVinci Resolve, Final Cut, or Premiere, ColorCard Pro ensures you always start from a true baseline.
Features
Device-calibrated accuracy – Color patches and grey cards are corrected using verified colorimetric data for each iPhone model.
Dynamic grey card brightness – The app adapts automatically to ambient light for consistent reference values in any lighting.
True color reference patches – Includes RGB and HEX values for each patch to match grading software or LUT adjustments.
Calibrated to Display-P3 – Targets the professional D65 color temperature standard used in editing pipelines.
Simple, fast workflow – One tap to open full-screen cards, swipe down to return.
Compact & durable – Replace fragile paper cards with a self-illuminated, perfectly uniform digital reference.
How to Use
On set: Hold the Color or Grey Card in your shot for a few seconds at the start of each scene.
In post: Use the captured frame to set white balance and match color primaries. Adjust temperature and tint until neutrals align visually or numerically with the provided patch values.
Reference values: Toggle patch IDs and RGB/HEX codes for direct matching in grading software.
Why It Matters
Even minor color drift can ruin footage continuity. Camera Butter’s calibration process uses real-world display measurements and public reference data to compensate for every supported iPhone model — giving you a repeatable, reliable reference anywhere.
