Hueaura Pro

Extracts color palettes from your photos. Photograph a flower, a fabric, a fruit or a building, or pick an image from your gallery, and Hueaura finds its main colors and subtle shades, with exact values you can copy into your own work.

HOW IT WORKS
• Take a photo or import one from your gallery
• Rotate it and drag a frame around the area you want to analyze
• Choose a mode and how many colors you want (2 to 16)
• Refine the result, save it to your library and export it

EXTRACTION MODES
• Dominant: the colors that take up the most of the image
• Detailed: secondary colors and subtle variations
• Balanced: an even overview of the whole image
• Vibrant: the most saturated colors first
• Soft: muted and pastel tones
• Natural: colors true to the subject
• Monochromatic: a range of tones from the main color family

Analysis runs on your device. Colors are grouped in the CIELAB color space, and near-duplicates are merged using the CIEDE2000 color difference formula. Advanced options let you control how distinct the colors should be and ignore near-white or near-black backgrounds.

COLOR PICKER
Tap or drag anywhere on the image to read a color. A magnifier shows the pixels under the cursor, and you can zoom in for precision. Add picked colors to your palette or replace existing ones.

COLOR DETAILS
Each color shows HEX, RGB, HSL, HSV, CIELAB, XYZ, LCh, relative luminance, its contrast against white and black, and an approximate descriptive name. Every value can be copied with one tap.

TOOLS
• Harmonies: complementary, analogous, triadic, tetradic, split complementary, square and monochromatic
• Variations: lighter, darker, tints, shades, tones, saturation steps, and warmer or cooler shifts
• Contrast checker: WCAG contrast ratio with pass/fail results for AA and AAA, normal and large text, plus a live text preview

PALETTE EDITOR AND LIBRARY
• Add, edit, reorder, sort and remove colors
• Edit colors by HEX, RGB or HSL
• Name palettes, add notes and tags, and group them into collections
