About Color Picker
The GuruAlpha Color Picker lets you select any color from an interactive spectrum and get its HEX, RGB and HSL values instantly. Click anywhere on the color gradient to pick a color, adjust saturation and lightness with sliders, or enter a known color code to preview it. It is an essential tool for web designers, graphic artists and developers who work with colors daily.
Color picking is a fundamental task in design workflows. Whether you are building a website, designing a logo, creating marketing materials or editing photos, you need to select precise colors and obtain their technical values for use in CSS, design software or print specifications. The Color Picker provides all three major color formats simultaneously, eliminating the need for separate conversion tools.
The interactive color spectrum displays the full visible color range in a two-dimensional gradient. The horizontal axis represents hue (0-360 degrees on the color wheel), and the vertical axis represents saturation. A separate lightness slider controls how bright or dark the selected color is. This intuitive interface lets you visually find the exact color you want, then copy its values for use in your project.
The tool also includes a palette of commonly used colors organized by category: web-safe colors, material design colors, Tailwind CSS colors and Pantone reference colors. Click any preset to instantly load it into the picker. This preset library speeds up color selection for common use cases and ensures consistency with established design systems.
The contrast checker integration shows the selected color's contrast ratio against white and black backgrounds, helping you choose colors that meet WCAG accessibility standards. A contrast ratio of at least 4.5:1 is required for normal text (WCAG AA), and 7:1 for enhanced accessibility (WCAG AAA). This feature prevents accessibility issues before they reach production.

Frequently Asked Questions About Color Picker
What is the difference between HEX, RGB and HSL?
HEX uses a 6-digit hex code (#FF5733). RGB defines colors by red, green, blue values (0-255 each). HSL uses Hue (0-360), Saturation (0-100%) and Lightness (0-100%).
What is WCAG contrast ratio?
WCAG defines minimum contrast for readability. AA requires 4.5:1 for normal text. AAA requires 7:1. The tool shows the ratio for your selected color against white and black.
Can I enter a color code directly?
Yes. Enter HEX (#FF5733), RGB (rgb(255,87,51)) or HSL (hsl(9,100%,60%) values and the picker will display that color.
Are the presets from real design systems?
Yes. Presets include Web Safe colors, Google Material Design, Tailwind CSS and Pantone reference colors.
