A Color Converter mathematically translates color representations between different color models (such as HEX hexadecimal strings, RGB decimal integers, HSL degree/percent tuples, HSV brightness models, CMYK print percentages, OKLCH perceptual spaces, HWB paint models, and CIE LAB standards). All conversions run 100% locally in your browser memory.

RGB (Red, Green, Blue) is an additive color model used for screen displays. HSL (Hue, Saturation, Lightness) represents colors based on human perception. CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive color model designed for physical ink printing.

The 'A' in RGBA and HSLA stands for Alpha, representing the color's opacity/transparency layer ranging from 0.0 (fully transparent) to 1.0 (fully opaque) or 0% to 100%.

The contrast ratio evaluates relative luminance using the W3C Web Content Accessibility Guidelines (WCAG 2.1) formula. A ratio of 4.5:1 is required for AA normal text compliance (3.0:1 for large 18pt+ text), while 7.0:1 is required for AAA compliance.

OKLCH is a perceptual color space designed to align with human vision. Unlike HSL, changes in hue in OKLCH maintain uniform perceived lightness and chroma, preventing perceptual brightness spikes and making it ideal for modern design systems and wide-gamut displays.

The simulator applies the peer-reviewed Brettel and Viénot transformation matrices in LMS cone color space to accurately model Protanopia (red-blind), Deuteranopia (green-blind), Tritanopia (blue-blind), and Achromatopsia (monochrome), allowing designers to verify palette readability before shipping.

HWB (Hue, Whiteness, Blackness) provides an intuitive paint-mixing interface standardized in CSS Color Level 4. CIE LAB (L*a*b*) is a device-independent standard designed to approximate human vision under a standard D65 illuminant, widely used in colorimetry, image processing, and print workflows.

On supported Chromium browsers, the tool leverages the HTML5 EyeDropper API (window.EyeDropper) to let you sample any pixel color directly from your screen (including desktop windows outside the browser). No plugins or permissions are required.

Yes. Telekit Color Converter operates entirely client-side using standard JavaScript color algorithms. Your color codes, hex inputs, and exported reports are never sent to external servers or logged remotely.

You can export high-resolution PNG swatches, scalable SVG vector graphics, RFC 4180 CSV specifications, structured JSON audit reports, and Markdown summary tables with customizable filenames. Standard hardware shortcuts include 'Alt+P' for DevToys Smart Clipboard Auto-Detect (parsing HEX, RGB, HSL, CMYK, CSS variables, and raw text), 'Alt+D' to star/favorite the tool in local storage, 'Alt+1' through 'Alt+6' for 1-Click Quick Copy across 6 formats, '/' to focus input, 'Ctrl+Enter' to copy active hex, 'Alt+V' to toggle 2-column studio layout, 'Alt+S' for the Developer API Code Studio across 9 languages with standalone script downloads, 'Alt+R' for random colors, 'Alt+I' to invert, 'Alt+L' / 'Alt+M' to lighten/darken, 'Alt+K' or '?' for the shortcuts guide, and 'Esc' to close dialogs or reset.
