Color Palette Extractor
Extract and generate color palettes from images, websites, and designs.
Instructions
When a user needs to extract colors from a source:
-
Identify Source Type:
- Image file (PNG, JPG, SVG)
- Website URL
- Screenshot
- Design mockup
- Existing color code to build palette from
-
Extract Colors:
From Image:
- Analyze pixel data
- Identify dominant colors
- Group similar shades
- Calculate color frequency
- Sort by prominence
From Website:
- Fetch and parse CSS
- Extract color values from stylesheets
- Identify brand colors
- Find accent colors
- Detect text/background colors
Color Clustering:
- Use K-means clustering
- Group similar colors
- Typically extract 5-10 dominant colors
- Ignore near-white/near-black unless significant
-
Generate Color Palette:
Primary Palette (5-10 colors):
- Most dominant color
- 2-3 supporting colors
- 1-2 accent colors
- Background color
- Text color
Extended Palette:
- Light and dark variations
- Tints (add white)
- Shades (add black)
- Tones (add gray)
- Generate 50, 100, 200...900 scales
-
Color Harmony Analysis:
Generate complementary schemes:
- Monochromatic: Variations of single hue
- Analogous: Adjacent colors on wheel
- Complementary: Opposite colors
- Triadic: Three evenly spaced colors
- Split-complementary: Base + two adjacent to complement
- Tetradic: Four colors (two complementary pairs)
-

Contrast Ratios (WCAG 2.1):
Text on Background: #1E293B on #F8FAFC: 14.2:1 ✅ AAA (excellent)
Primary on Background: #3B82F6 on #F8FAFC: 4.8:1 ✅ AA (good)
White text on Primary: #FFFFFF on #3B82F6: 4.6:1 ✅ AA (good)
Accent on Background: #10B981 on #F8FAFC: 3.2:1 ⚠️ AA Large text only
Recommendations: • Use darker shade of accent for small text • Primary button text should be white (#FFFFFF) • Consider #047857 for better contrast

It's designed for developers to compare model quality, track training progress, or report academic results. The tool supports various backends including HuggingFace and vLLM models.
sglang
メタSGLang is a high-performance LLM serving framework that specializes in fast, structured generation for JSON, regex, and agentic workflows using its RadixAttention prefix caching. It delivers significantly faster inference, especially for tasks with repeated prefixes, making it ideal for complex, structured outputs and multi-turn conversations. Choose SGLang over alternatives like vLLM when you need constrained decoding or are building applications with extensive prefix sharing.
