Screenshot to Color Palette: How Site Import Works
Palettero's Import Site feature analyzes uploaded screenshots to automatically extract a functional color palette, recommend matching catalog fonts, and detect page structure for live editing.
What does Palettero extract from a screenshot?
When you drop a screenshot into the import tool, our client-side analysis engine processes the decoded pixels directly on your device:
- Color Roles: Detects background canvas colors, text colors, and prominent interactive accents using OKLab color clustering, filtering out photographic noise and gradient artifacts.
- Typography Suggestions: Analyzes stroke widths, letter proportions, and serif versus sans-serif characteristics to match fonts from our curated typography catalog.
- Layout Structure: Identifies regions like hero areas, sidebars, metric grids, and navigation bars to map the design to an appropriate template.
What are the limitations of screenshot analysis?
Screenshots are static raster images, meaning the engine performs statistical inference rather than inspecting raw source code:
Approximation, not pixel clone
Import extracts design DNA (palette, contrast, type personality) and maps it into clean, responsive templates. It does not reproduce custom illustration art or proprietary SVG logos.
Anti-aliasing and compression noise
JPEG compression can blend sharp borders into subtle gradient fringes. The engine masks photo regions, but clean PNG screenshots always yield higher color precision.
Local device privacy
Initial image quantization happens locally in your browser. If AI vision layout analysis is used, user consent is explicitly requested before sending reduced images.
How do you capture high-quality screenshots for import?
For the most accurate palette extraction, follow these guidelines when capturing your source image:
- Capture full desktop viewports: Take screenshots at standard desktop resolutions (1280px to 1920px wide) rather than narrow mobile crops.
- Use lossless PNG format: PNG preserves exact hex colors without JPEG block compression or color smudging.
- Include representative components: Ensure headers, buttons, cards, and text paragraphs are visible in the capture.
- Avoid heavy popups or cookie banners: Close modal dialogs, cookie consent banners, or chat overlays before capturing.
