Flesh Master™ trains your eye to recognize, match, and break down colors at a glance—especially the complex tones found in human skin. This isn’t just a game. It’s a visual training tool built for artists who want to sharpen how they see. Using only Red, Yellow, Blue, and White, Flesh Master™ helps you identify the balance behind every skin tone: Is it more yellow? More red? More muted? Brighter? With repeated play, you begin to spot these differences instantly. Flesh Master™ is used by Oscar-, Emmy-, and BAFTA-winning makeup artists to improve their color accuracy on set. It was created by award-winning special effects artist and director Rod Maxwell, who served as Innovation Lead on films including Black Panther: Wakanda Forever and Disney’s live-action Moana. He has taught special effects and color theory for over a decade, helping artists refine how they see and mix color under real-world conditions. The app draws on real-world pigment behavior—not digital shortcuts—so what you learn applies directly to makeup, painting, photography, and color correction. Now fully rebuilt for the latest iOS and watchOS, the app includes a mini-game for Apple Watch, letting you train your eye anywhere, anytime. Flesh Master™ helps you: Break down colors into their red/yellow/blue components in a glance Understand how neutral browns come from orange + blue Visualize how tints evolve as white is added Match subtle skin tones more confidently and consistently Trusted by top professionals. Designed for artists who want to see deeper. (Not intended for users who are color blind.)
