Undertone - Color Analysis

Every image has a color structure. Undertone shows it to you: palette with proportions, harmony, temperature, value. On-device, for painters and designers.

Every image has a color structure. Undertone shows it to you.

Bring in any image, a photo, a painting, a screenshot. In seconds, the app breaks down the color structure underneath: palette, harmony, temperature, and value. The relationships that make an image feel right, made visible. All processing happens on your device. Your images never leave your device.

What you get with every analysis:

Palette with proportions. Not flat swatches. Dominant colors shown by actual weight. A 60% warm neutral with a 5% cool accent is a different palette than 50/50. Every color labeled with hex codes and painter-friendly names. Cadmium Yellow, not "Autumn Sunset Dream."

Color harmony. The relationship between your colors identified and named: complementary, analogous, triadic, split-complementary, tetradic, square, monochromatic, or honestly, none. Not every image has a clean harmony, and Undertone won't pretend. Colors plotted on a wheel so you can see the geometry.

Temperature map. A warm-cool overlay on your image that makes the invisible visible. Muddy shadows? Probably a temperature problem, warm paint leaking into your cools. Golden hour magic? Warm light forces cool shadows by contrast. Toggle the map on, and the thing you couldn't diagnose becomes obvious.

Value structure. Your image stripped to grayscale, divided into clear zones: light, mid-tone, dark. Value does more work than color. A painting with strong values and wrong colors still reads. This automates the painter's squint.

Built for people who work with color:

Painters studying a master painting at the museum, analyzing a reference before mixing, or diagnosing why the shadows look muddy.

Photographers translating a mood board into concrete editing decisions, or understanding why golden hour works so they can repeat it.

Designers extracting palettes from real-world references and showing clients why a color scheme works. With evidence, not "trust me."

Art students crossing the gap between intuition and understanding. Every analysis is a micro-lesson in color theory.

Every analysis is saved automatically. Your library becomes a personal color reference you can browse anytime.
