Free Online Color Picker Tool
Every design project starts with color. Whether you are matching a brand guideline, sampling a color from a screenshot, or exploring hues for a new website, you need accurate color values in the right format. Our free online color picker lets you select any color visually or by entering a value, and instantly converts it between HEX, RGB, and HSL — the three most common color formats used in web development and digital design.
Copy any color code with a single click and paste it directly into your CSS, design tool, or code editor. The tool updates all three formats in real time as you adjust the color, so you never have to manually convert between systems. Everything runs locally in your browser with no sign-up required.
How to Use the Color Picker
Click anywhere on the color spectrum to pick a hue, then adjust brightness and saturation using the sliders or input fields. Alternatively, type a known HEX code (e.g., #3b82f6) or adjust individual RGB values to dial in an exact color. All three format fields — HEX, RGB, and HSL — update simultaneously. Click the copy button next to any format to grab that value for use in your project.
Color Format Reference
- HEX: A six-digit hexadecimal code prefixed with # (e.g.,
#3b82f6). The most compact format, widely used in HTML, CSS, SVG, and design tools like Figma and Sketch. - RGB: Red, Green, and Blue channel values from 0–255 (e.g.,
rgb(59, 130, 246)). Native to CSS and essential when you need alpha transparency viargba(). - HSL: Hue (0–360°), Saturation (0–100%), and Lightness (0–100%) (e.g.,
hsl(217, 91%, 60%)). The most intuitive format for designers because you can lighten, darken, or desaturate a color without changing its hue.
Who Uses a Color Picker?
- Web developers grab exact color values for CSS, Tailwind config, and component libraries.
- UI/UX designers sample colors from mockups and convert between formats for handoff documents.
- Digital marketers match brand colors for email templates, social graphics, and ad creatives.
- Students and hobbyists learn how color values relate across different notation systems.
- Print designers use RGB values as a starting point before converting to CMYK for production.

Tips for Working With Color Codes
Use HEX for static colors in stylesheets and design tokens. Switch to RGB or HSL when you need programmatic control — HSL makes it easy to generate lighter and darker shades by adjusting only the lightness value. For accessibility, always check your text and background color pairings with a contrast checker to meet WCAG AA standards (4.5:1 ratio for normal text).
Frequently Asked Questions
Which color format should I use in CSS?
All three are valid in modern CSS. HEX is the most common for static colors in stylesheets. RGB is preferred when you need transparency via rgba(). HSL is ideal for creating color variations programmatically — adjusting lightness from 20% to 80% gives you a full range of shades from the same hue.
Can I enter a color manually?
Yes. Type any valid HEX code in the HEX field, or adjust the RGB sliders and number inputs. The visual picker and all other format fields update in real time to match your input.
What is the difference between RGB and HSL?
RGB describes a color by mixing red, green, and blue light channels. HSL describes the same color using hue (the base color on the wheel), saturation (intensity), and lightness (brightness). HSL is more intuitive for humans — saying "make it 20% lighter" maps directly to adjusting the L value.
Does this tool support alpha transparency?
This picker outputs solid colors without transparency. For alpha values, take the RGB output and use rgba() in CSS (e.g., rgba(59, 130, 246, 0.5) for 50% opacity), or use the 8-digit HEX format (#3b82f680) supported in modern browsers.
How do I match a color from an image?
Use your operating system's built-in color picker or a browser extension to sample a pixel color, then paste the HEX value into this tool to get all format conversions. Some design tools like Figma also include an eyedropper for direct sampling.
Are the color values accurate across devices?
The numerical values are mathematically precise, but how a color appears depends on your monitor's calibration and color profile. For critical brand work, verify colors on multiple screens and in your target medium (web, print, mobile).
