What is an Online Color Picker?

An online color picker helps web developers and designers find, convert, and experiment with colors across different formats. Whether you need a HEX code for CSS, an RGB value for a design tool, or an HSL value for dynamic color manipulation, this tool provides instant conversion between all major color formats.

Choosing the right colors is critical for web design — it affects readability, accessibility, and brand consistency. Our color picker runs entirely in your browser and lets you visually select colors or type exact values for precise control.

Frequently Asked Questions

Which color format should I use in CSS?

HEX (#FF5733) is the most common and widely supported. RGB is useful when you need alpha transparency (rgba(255, 87, 51, 0.5)). HSL is best when you want to programmatically adjust colors — it’s intuitive to change hue, saturation, or lightness independently.

How do I find accessible color combinations?

Ensure your text and background colors have a contrast ratio of at least 4.5:1 for normal text (WCAG AA). Use lighter/darker variations by adjusting the L value in HSL.
