How do I convert HEX to RGB?

Paste a HEX value like #2563eb and the tool splits it into its red, green and blue channels — rgb(37, 99, 235). Each pair of hex digits (25, 63, eb) is a 0–255 channel value: 0x25 = 37, 0x63 = 99, 0xeb = 235. The conversion is exact and runs in your browser.

What is the difference between RGB and HSL?

RGB describes a colour by its red, green and blue light components (0–255 each), which is how screens render it. HSL describes the same colour by Hue (0–360° on the colour wheel), Saturation (0–100%) and Lightness (0–100%), which is more intuitive for tweaking — e.g. lighten a colour by raising L without touching the hue. Both map to the exact same on-screen colour.

Are 3-digit HEX shorthand colours supported?

Yes. A 3-digit HEX like #1ce expands to the 6-digit form #11ccee by doubling each digit, then converts normally. The tool accepts both 3- and 6-digit HEX with or without the leading #.

Is my colour data sent to a server?

No. All HEX/RGB/HSL conversion runs locally in your browser with no upload or logging — useful when working on brand or design tokens you'd rather keep private.

How do I use these values in CSS?

All three formats are valid CSS: color: #2563eb;, color: rgb(37 99 235); and color: hsl(217 91% 53%);. Copy whichever your stylesheet or design system prefers — modern CSS accepts space-separated rgb()/hsl() and an optional alpha after a slash.

What Is a Color Converter?

A color converter is a tool that translates color values between different color representation formats. The three most common formats used in web design, CSS styling, and digital graphics are HEX (hexadecimal), RGB (red, green, blue), and HSL (hue, saturation, lightness). Each format represents the same color information in a different way, optimized for different use cases. Converting between these formats allows designers and developers to work with colors in whichever format is most convenient for their workflow. For example, a designer might pick a color from a color picker that outputs HSL, but then need to convert it to HEX to use in a CSS stylesheet. A color converter eliminates manual calculation and ensures accuracy across all three formats.

Understanding Color Formats

HEX (Hexadecimal)

HEX format represents colors as six hexadecimal digits (0–9, A–F) preceded by a hash symbol: #RRGGBB. The first two digits represent the red channel, the next two represent green, and the last two represent blue. Each pair can range from 00 (no intensity) to FF (maximum intensity). HEX is compact and widely supported in web browsers and CSS. You can also use shorthand 3-digit HEX format where each digit is doubled (e.g., #36F equals #3366FF).

RGB (Red, Green, Blue)

RGB format specifies colors by combining three primary light colors: rgb(R, G, B) where each value ranges from 0 to 255. A value of 0 means no light from that color channel, while 255 means maximum intensity. RGB is intuitive for understanding additive color mixing and is the format used internally by digital displays and programming languages.

HSL (Hue, Saturation, Lightness)

HSL format separates color into three perceptual dimensions: hsl(H, S%, L%). Hue is the color itself, represented as an angle from 0° to 360° on a color wheel. Saturation (0–100%) controls color intensity—0% produces gray, 100% produces a vivid color. Lightness (0–100%) controls brightness—0% is black, 50% is the “normal” color, and 100% is white. HSL is intuitive for designers because adjusting saturation or lightness feels more natural than manipulating RGB values.

Worked Example

Consider the color Indigo Blue, represented as:

HEX: #3366FF
RGB: rgb(51, 102, 255)
HSL: hsl(225, 100%, 60%)

All three formats describe the same color. The HEX value 33 converts to RGB 51 (first pair of digits), 66 becomes 102 (second pair), and FF becomes 255 (third pair). In HSL, the hue angle 225° lands in the blue region of the color wheel, saturation is at maximum 100% for vivid color, and lightness at 60% makes it bright but not washed out.

Use Cases

Web Design & CSS: Designers often use design tools that output colors in HSL or HEX, then convert to use in stylesheets or CSS-in-JS frameworks. A color converter ensures the exact same color is applied across all contexts.

Design Systems & Accessibility: Design systems document color palettes in one format (often HEX for consistency), but developers may need RGB or HSL for dynamic calculations, animations, or accessibility compliance checks (e.g., evaluating contrast ratios).

Image Processing & Graphics: Some graphics libraries prefer RGB for pixel manipulation, while others (like canvas APIs) support HSL for intuitive color adjustment. Converters bridge these differences seamlessly.

Standards and References

Color representation in web technologies is standardized by the CSS Color Module Level 4 specification from the World Wide Web Consortium (W3C). This standard defines all three color formats and ensures consistent color rendering across browsers and devices.

Frequently Asked Questions

Which color format should I use?

Use HEX for simplicity and broad compatibility, especially in CSS and design systems. Use RGB when working with graphics programming or pixel-level manipulation. Use HSL when you need intuitive control over lightness or saturation—for example, creating variations of a color by adjusting only the lightness value.

Does the conversion lose precision?

No. HEX and RGB are mathematically equivalent—each RGB value maps directly to two hexadecimal digits. HSL is calculated from RGB using standard algorithms and maintains full precision. Rounding occurs only for display purposes; the underlying color remains accurate.

Can I use these formats interchangeably in CSS?

Yes. Modern browsers support HEX, RGB, and HSL in CSS color properties like color, background-color, and border-color. All three formats produce identical results and can be mixed within the same stylesheet.
