Is my uploaded image sent to a remote server?

No. ColorKit operates 100% client-side within your web browser using HTML5 Canvas APIs. Your images, personal photos, and proprietary UI designs never leave your device and are never transmitted to or stored on any server.

What color formats are supported?

ColorKit automatically calculates values across HEX (#RRGGBB), RGB (Red, Green, Blue), HSL (Hue, Saturation, Lightness), HSV (Hue, Saturation, Value), CMYK (Cyan, Magenta, Yellow, Black), modern OKLCH, and native CSS Variables.

How does the dominant color palette extraction work?

When an image loads, our in-memory quantization algorithm analyzes the pixel data across the graphic, groups similar RGB values into discrete color bins, filters out transparent areas, and selects the top 8 most prominent color clusters to formulate a balanced palette.

Can I export the extracted palette to CSS or Tailwind?

Yes. Click the 'Export Palette' button above the dominant palette swatches to copy ready-to-use CSS Custom Properties (--color-1 through --color-8), Tailwind CSS color configuration objects, or raw JSON arrays.

Comprehensive Guide to Image Color Extraction & Digital Color Models

Digital graphics are composed of matrices of microscopic pixels, each representing a precise blend of light intensities. Whether you are reverse-engineering a brand identity from a screenshot, sampling UI elements from high-fidelity mockups, or converting photographic textures into digital palettes, understanding color spaces is essential.

tuneThe HTML5 Canvas Coordinate Math

When you hover across an image displayed on high-density (Retina/4K) monitors, CSS styling scales the rendered bounding box. ColorKit recalculates exact pixel vectors using natural width ratios:

const scaleX = canvas.naturalWidth / boundingBox.width;
const pixelX = Math.floor((cursor.x - boundingBox.left) * scaleX);

This prevents chromatic aberrations and guarantees that the RGB data retrieved by ctx.getImageData() corresponds to the uncompressed raw pixel.

hubColor Quantization & Clustering

To generate a cohesive dominant color palette from a high-resolution photo with millions of unique pixels, an image must be intelligently clustered. ColorKit uses a multi-step quantization pipeline:

Sub-sampling: Downsampling to 160×160 in memory to preserve compute power.
Binning: Grouping visually neighboring RGB tuples into discrete 24-step color bins.
Thresholding: Rejecting alpha transparency and low-saturation outliers.
Ranking: Extracting the top 8 distinct modal clusters for maximum aesthetic contrast.

Understanding Output Color Spaces

Depending on whether your workflow targets web development, print production, or modern wide-gamut displays, each color notation serves a specific purpose:

HEX (Hexadecimal): A six-character hexadecimal representation (e.g. #4F46E5) used predominantly in HTML and CSS. The first two characters define Red, the middle two Green, and the last two Blue on a 0–255 scale (00 to FF).
RGB & RGBA: Additive color model representing the intensity of red, green, and blue phosphor light. Perfect for WebGL shaders, Canvas, and CSS rgb(r, g, b) declarations.
HSL & HSV: Cylindrical coordinate representations that separate chromatic hue (0° to 360°) from saturation and luminance/lightness. Ideal for creating hover states and harmonic tint variations.
CMYK: Subtractive ink model (Cyan, Magenta, Yellow, Key Black) tailored for physical commercial offset printing.
OKLCH: A perceptually uniform color space supported in CSS Color Module Level 4. Unlike sRGB, OKLCH maintains consistent human perceived lightness across all hues, preventing muddy transitions in gradients.

Ensuring WCAG Accessibility with Extracted Palettes

When extracting colors from branding mockups or photography to build UI elements, verify that your text meets the Web Content Accessibility Guidelines (WCAG 2.1):

WCAG Level AA: Requires a minimum contrast ratio of 4.5:1 for regular body text and 3.0:1 for large headings (18pt+ or 14pt bold).
WCAG Level AAA: Requires an enhanced contrast ratio of 7.0:1 for standard text.

You can test your sampled colors directly with our integrated WCAG Contrast Checker.
