Color Toolkit
Pick colors from images, extract palettes, convert HEX/RGB/HSL/CMYK, generate color schemes, and check color-blind accessibility — free, private, all in your browser.
1. Current Color
HEX: #E07A2C\nRGB: rgb(224, 122, 44)\nHSL: hsl(26, 74%, 53%)\nCMYK: C:0 M:46 Y:80 K:12
2. Workspace Mode
Drag & drop an image here, or click to browse
3. Color Scheme Generator
4. Shades & Tints
Tints (lighter)
Shades (darker)
5. Color-Blindness Simulation
This is an approximate simulation for design guidance, not a medical diagnostic tool.
6. Session Color History
7. Custom Palette & Export
Your palette is empty — use "+ Add to Palette" anywhere in this tool to build one.
How to Use Color Toolkit
- Pick a Mode: Pick from Image, Extract Palette, or Convert Formats.
- Set a Current Color: Click any pixel, swatch, or type a HEX/RGB/CMYK value.
- Generate a Scheme: Try Complementary, Analogous, Triadic, Split-Complementary, or Monochromatic.
- Check Shades & Tints: A 10-step lighter and darker scale updates automatically.
- Preview Accessibility: Simulate Protanopia, Deuteranopia, Tritanopia, or Grayscale.
- Build a Palette: Click "+ Add to Palette" on any swatch you want to keep.
- Export: Copy CSS variables, JSON, a HEX list, or download a swatch sheet.
Why Use This Tool
An all in one color design tool palette picker hex converter tool means not switching between three separate tabs to sample a color, pull a palette from a photo, and check its CMYK print value. This complete color toolkit picker palette extractor cmyk hex free tool keeps one shared Current Color that every part of the workspace reads from and updates, so a color picked from an image is instantly ready to convert, build a scheme from, or check for print.
How It Works
This unified color workspace hex rgb cmyk extraction tool uses the same trusted eyedropper, palette extraction, and CMYK conversion logic as ToolNest's original three color tools, now sharing one central color state. Picking a pixel, clicking an extracted swatch, or typing a HEX or RGB value all update the same Current Color panel, which then automatically recalculates connected schemes, shade and tint scales, and the accessibility simulation preview.
Key Features
As a professional color toolkit for designers web and print tool, five color scheme types calculate instantly from the current color using standard hue-rotation math: Complementary, Analogous, Triadic, Split-Complementary, and Monochromatic. A 10-step lighter tint scale and 10-step darker shade scale update automatically for every color you select, and a color-blindness simulation preview approximates how your palette appears under Protanopia, Deuteranopia, Tritanopia, or Grayscale. A running custom palette can be exported as copy-ready CSS variables, structured JSON, a plain HEX list, or a downloadable swatch sheet image, and a session color history keeps your last 20 picks one click away.
Common Use Cases
A designer building a website color system picks a brand color from a logo image, generates its Analogous scheme for supporting UI colors, and exports the whole set as CSS variables ready to paste into a stylesheet. Someone preparing print materials extracts a palette from a product photo, checks each color's CMYK breakdown in Convert Formats, and confirms the palette still reads clearly under the color-blindness simulation before finalizing artwork. A design student explores how a single brand color transforms into five different scheme types to compare options before choosing a final direction.
Tips
The color-blindness simulation is an approximation meant to guide design decisions, not a diagnostic tool — when in doubt, pair simulated colors with the Accessibility Contrast Checker to confirm text stays readable. Building up a custom palette as you go (using the small + button on any swatch) makes exporting a finished, curated set far easier than trying to remember which colors you liked from an extracted palette or scheme.
Frequently Asked Questions
Can I extract palettes, pick individual colors, and convert CMYK in one session?
Yes, all three modes share the same Current Color, so switching between Pick from Image, Extract Palette, and Convert Formats keeps your work connected.
How accurate is color extraction from photos for design matching?
Extraction groups similar pixel colors and returns the most common clusters, which works well for dominant colors but may simplify subtle gradients or lighting variations.
Does the toolkit support both print (CMYK) and web (HEX/RGB) workflows?
Yes, the Current Color panel always shows HEX, RGB, HSL, and CMYK together, and Convert Formats lets you start from any of them.
Are uploaded images stored or processed on a server?
No, all image processing for picking colors and extracting palettes happens locally in your browser.
Can I save custom color palettes for future projects?
Within a session, yes — build a palette with the + Add to Palette button and export it as CSS, JSON, a HEX list, or a swatch sheet image to reuse in your project files.
How do I ensure color consistency between print and web designs?
Check the CMYK values shown in the Current Color panel alongside the HEX/RGB values so you have both the print and web equivalent of the same color on hand.
What file formats are supported for import/export?
Images can be uploaded as JPG, PNG, or WebP for picking and extracting; palettes export as CSS variables, JSON, a plain HEX list, or a PNG swatch sheet.
Is the color toolkit mobile-friendly for on-site design work?
Yes, all controls including the eyedropper, mode tabs, and export buttons are usable on a touchscreen.
What color schemes can I generate from a single color?
Complementary, Analogous, Triadic, Split-Complementary, and Monochromatic schemes all calculate instantly from your current color.
Can I preview how my palette looks to someone with color blindness?
Yes, the Color-Blindness Simulation section shows an approximate preview for Protanopia, Deuteranopia, Tritanopia, and Grayscale.
