Frequently Asked Questions
How does the eyedropper color picker sample colors from external websites or desktop apps?
The tool leverages the native Chromium `EyeDropper` API, which allows users to open a screen magnification loupe and sample exact RGB/HEX pixel values from any point on their display, including desktop applications, video players, and web pages.
What is the difference between HSL and RGB color models?
RGB (Red, Green, Blue) is an additive hardware color model describing light intensities (0-255). HSL (Hue, Saturation, Lightness) is a cylindrical coordinate representation that aligns more naturally with human perception, making it easier to lighten, darken, or desaturate colors systematically.
How does the WCAG color contrast checker calculate accessibility compliance?
The checker calculates the relative luminance of foreground and background colors according to WCAG 2.1 guidelines. A contrast ratio of at least 4.5:1 is required for normal text (Level AA) and 7:1 for enhanced accessibility (Level AAA).
Can I extract dominant color palettes from an uploaded photo?
Yes. Upload any image into the tool to run a client-side color quantization algorithm (Median Cut / k-means) that extracts dominant color swatches and generates exportable CSS color palettes.
