About Smart Color
Smart Color is a free color palette platform built for people who work with color every day — designers picking brand colors, developers implementing design systems, illustrators exploring new combinations, or anyone putting together a mood board for a project.
The site started because most existing palette tools either showed you pre-made palettes with no way to search them properly, or gave you a generator with no library to browse. We wanted both in one place, plus a few things we kept wishing other tools had.
What You Can Do Here
Browse Palettes by Theme
The palette library is organized by color and season — blue, green, autumn, neon, and more. Each palette shows its hex codes upfront so you can copy them straight into your CSS, Figma, or any design tool that takes hex or RGB values. You can also search across the entire library by keyword.
Generate Palettes with AI
Describe what you need in plain language — "warm sunset tones for a bakery website" or "muted earth tones with a pop of teal" — and the AI palette generator will create a matching palette. It runs on GPT-4o-mini and gives you 5–10 colors per generation. You get a set number of free generations per day so the service stays available for everyone.
Pick Colors from Any Image
The image color picker lets you upload a photo or screenshot and extract the exact colors from it. This is useful when you have a reference image — a photo, a piece of art, a screenshot of a site you like — and want to pull the specific hex codes out of it.
Replace Colors in Images
The color replacement tool lets you swap one color for another in any uploaded image. Upload your image, pick the color you want to change, choose the replacement, and adjust the tolerance to control how much gets replaced. It runs entirely in your browser — nothing gets uploaded to a server.
Create and Share Your Own Palettes
Anyone can create a palette and add it to the library. Pick your colors, give the palette a name and tags, and it goes live for others to find and use. No account required — just build and share.
How It Works
The front end is built with Next.js and runs on Vercel. Palette data lives in a PostgreSQL database hosted on Supabase. The AI generation runs through a serverless backend that handles rate limiting and credit tracking so the OpenAI costs stay manageable.
Everything on the site is free to use. The AI generator has a daily limit per user to keep costs sustainable, but browsing, searching, creating palettes, and using the image tools are all unlimited.
