Gray Card
Learn Color Accuracy Through Practice
Built for educational purpose
Exp3rt Gray Card is an educational reference tool designed for photographers, videographers, editors, and students who want to improve their understanding of light, color, and white balance.
It helps you train your eye, observe color shifts in different lighting conditions, and build a stronger foundation in color calibration.
This app is intentionally created for learning, practice, and visual understanding — making it ideal for classrooms, workshops, and self-study.
Educational Purpose
Gray Card is not a replacement for a physical 18% gray card.
It serves strictly as a learning aid, training reference, and visual comparison tool.
For critical or professional color-sensitive work, a real gray card remains essential.
Perfect for:
Photographers & Students — Learn how to evaluate and correct white balance.
Videographers — Explore lighting differences and color references in one place.
Editors — Strengthen your perception of neutral tones and color accuracy.
Hobbyists & Educators — Use it in lessons, demonstrations, or hands-on practice.
Why Use Gray Card?
Learn by Doing — See how light and color interact in real scenarios.
Build Confidence — Understand what “correct color” looks like before your shoot.
Improve Accuracy — Better color knowledge leads to more efficient editing.
