What is the difference between RGB and HSL?

RGB describes color by the intensity of its red, green, and blue components (0-255 each). HSL describes the same color by hue (a 0-360° position on the color wheel), saturation (0-100% intensity), and lightness (0-100% closeness to white or black) — a model most people find more intuitive for adjusting shade and tint.

When would I use HEX vs RGB in CSS?

Both are valid and equally supported. HEX (#FF5733) is shorter and common for solid colors defined once. RGB becomes necessary when you need transparency via its rgba() form, e.g. rgba(255,87,51,0.5), since plain 6-digit HEX has no alpha channel.

Can I type a CSS color name like "tomato" or "rebeccapurple"?

Not directly — this tool works from HEX input. Look up the hex equivalent of the named color first (tomato is #FF6347) and paste that in; the tool will then give you its RGB and HSL equivalents.

Why do I need HSL if HEX already works fine?

HSL makes programmatic color manipulation far easier. To create five shades of the same hue, you just change the lightness value while keeping hue and saturation constant — doing the equivalent adjustment in HEX or RGB requires recalculating all three channels by hand.

Does this tool support alpha/transparency values?

The core conversion focuses on solid HEX, RGB, and HSL values. If you need an alpha channel, you can manually append it to the RGB output as rgba(r, g, b, alpha) or to HSL as hsla(h, s%, l%, alpha) — both are valid CSS.

Is 3-digit hex shorthand like #F53 supported?

Yes. The tool automatically expands shorthand hex (#RGB) to its full 6-digit equivalent (#RRGGBB) by duplicating each digit before running any conversion, matching how browsers interpret shorthand hex in CSS.

Is my color data sent to a server?

No. All parsing and math happens locally in your browser using plain JavaScript — nothing about the color you enter is ever transmitted or logged.

Can I use the output directly in Tailwind CSS?

Yes. The HEX and RGB outputs can be dropped straight into a Tailwind arbitrary value like bg-[#6366f1] or bg-[rgb(99,102,241)], and the HSL output works well if you're defining custom CSS variables for a Tailwind theme extension.

Why does my converted HSL lightness look different from what I expected?

Lightness in HSL is calculated relative to the color's own maximum and minimum channel — a very saturated pure red and a muted brownish-red can have very different lightness values even if they look similarly "bright" to the eye, because HSL lightness is a mathematical property, not a perceptual one.

What is Color Converter?

Color Converter is a free online tool that translates a single color between HEX, RGB, and HSL notation at the same time. Pick a color with the native browser color picker or type a hex code directly, and all three representations — plus a live preview swatch — update immediately. Every value comes with its own copy button so you can grab exactly the syntax your stylesheet, design tool, or codebase expects.

These three formats all describe the same underlying color, just structured differently for different purposes. HEX (#RRGGBB) packs red, green, and blue into a compact six-character string using hexadecimal pairs — it's the format most design tools export by default and the shortest to type for a solid color. RGB spells out the same three channels as plain decimal numbers from 0-255, and its rgba() variant adds a fourth alpha channel for transparency, which HEX alone can't express without an extended 8-digit form. HSL takes a completely different approach: instead of channel intensities, it describes color the way a human actually thinks about it — hue as a position on a 360° color wheel, saturation as how vivid or muted the color is, and lightness as how close it sits to black or white.

That distinction matters in practice. If you're building a design system and want five shades of the same brand blue, HSL makes it trivial — keep hue and saturation fixed and step lightness up or down in increments. Trying to do the same thing by eyeballing RGB or HEX values is much harder because the three channels don't correspond to "lighter" or "darker" in any intuitive way. Conversely, HEX remains the most compact and most widely supported format for pasting a color once into CSS, Figma, or a config file.

This tool also matters for cross-tool workflows: a designer hands you a HEX value from Figma, but your CSS custom properties are defined in HSL for easier theming, or you need the RGB breakdown to compute a WCAG contrast ratio by hand. Rather than doing the arithmetic yourself, paste the value in and read off whichever format you need. Everything runs client-side in your browser — no color values are ever sent to a server.

How It Works

The tool first normalizes your hex input, expanding 3-digit shorthand (#RGB) to full 6-digit form (#RRGGBB) if needed, then parses it into red, green, and blue integer channels (0-255) using base-16 parsing on each byte pair. From there it applies the standard RGB-to-HSL formula: it finds the maximum and minimum channel values to compute lightness, derives saturation from the spread between those values relative to lightness, and determines hue based on which channel (R, G, or B) was the maximum. All three outputs — HEX, RGB, HSL — are then formatted exactly as you would write them in a CSS file, and the whole calculation runs synchronously in JavaScript with no network request involved.

How to Use

1
Enter a hex color value
Type a hex code into the input field — either 3-digit shorthand (#F53) or full 6-digit form (#FF5733).
2
Or pick visually
Click the color swatch to open your browser's native color picker and select a color by eye.
3
Convert
Click Convert Color. The RGB and HSL equivalents are calculated and displayed alongside a live preview swatch.
4
Check the preview
The large swatch above the results shows exactly how the color renders, useful for confirming it matches what you intended.

📐

Design System Maintenance

Translate colors when moving from a Figma export (usually HEX) to HSL-based CSS custom properties, which make building light/dark theme variants far easier.

🖼️

Image Editing Workflows

Get the exact RGB breakdown of a color you sampled in Photoshop, GIMP, or a photo editor so you can reproduce it precisely in code.
