How this social media color palette generator works
Start from a photo or a hex
Upload a JPG, PNG, or WebP (up to 10MB), or type a 3- or 6-digit hex. The social media color palette generator resizes in memory, samples pixels, and never stores your file.
Pick a harmony rule
Choose Analogous, Complementary, Triadic, Monochromatic, Compound, or Shades. The generator maps your dominant hue through classic harmony formulas — no generative AI.
Copy, export, apply
Swatches show approximate color names, hex values, and 60-30-10 roles. Copy all hex codes or download.txt /.json named socialrails-color-palette-[timestamp] for your next post batch.
Why use this social media color palette generator?
Image extraction with K-means clustering
Upload a brand photo, product shot, or mood board and the generator samples dominant hues automatically. K-means clustering finds the colors that actually appear in your image, not random AI guesses.
Six harmony rules for feed-ready palettes
Analogous palettes feel soft and cohesive for lifestyle feeds. Complementary and Triadic options add contrast for covers and CTAs. Monochromatic and Shades keep minimalist brands on track.
60-30-10 roles with hex export
Each of the five swatches includes a suggested role — primary, secondary, accent — following the 60-30-10 design rule. Copy individual hex codes or export the full palette as.txt or.json.
Private, deterministic color tools
The tool uses no LLM calls and does not store images on disk. Typical palettes are ready in seconds, subject to a 10-request-per-minute rate limit.
