HEX to LAB Converter for Browser Color Conversion Tool
HEX to LAB converts a color between hexadecimal and L*a*b* in real time, with either side editable. It accepts short HEX such as #abc, RGB notation such as rgb(1 2 3 / 50%), and named colors. View a color swatch, copy a ready-to-paste CSS line, and check for an out-of-gamut warning when a color falls outside sRGB.
HEX to LAB is a browser-based color converter for turning a hexadecimal color into an L*a*b* value. It also supports live two-way editing, so you can change either side and see the other update. A color swatch, a ready-to-paste CSS line, and an out-of-gamut warning make it easier to review the result as you work.
Enter a color to see its conversion. Although the tool is called HEX to LAB, its parser is forgiving: it accepts short HEX such as #abc, RGB notation such as rgb(1 2 3 / 50%), and named colors. The conversion updates as you edit either field, and the tool warns when a color falls outside sRGB. You can use the displayed L*a*b* result or copy the CSS line.
HEX and LAB represent colors in different ways. HEX is a compact notation for specifying a color, while L*a*b* represents color using lightness and two color-opponent dimensions. Converting between them is useful when you need to move a color into a system that expects a different representation, check values you have been given, or prepare color details for code and documentation.
HEX to LAB runs entirely in your browser. Your input is processed on your device; nothing is uploaded, stored, or sent to a server. Once the page has loaded, conversion works offline, and no signup is required. The tool is free to use.
This converter can help developers, DevOps engineers, and anyone who needs to inspect or transfer color values between formats. Use it to check a conversion before adding a value to code, share a color in a ticket, or compare the HEX and LAB representations without retyping the result.
Step 1: Enter a color in the HEX field. The parser also accepts short HEX such as #abc, RGB notation such as rgb(1 2 3 / 50%), and named colors.
Step 2: Review the live L*a*b* result. The tool updates the other side when you edit either color field.
Step 3: Check the swatch to see the color represented by your current input and result.
Step 4: Look for an out-of-gamut warning if the color falls outside sRGB.
Step 5: Copy the L*a*b* value or the ready-to-paste CSS line for your code or notes.
Use case: Move a hexadecimal color into a system that only accepts L*a*b*. The live conversion makes it easy to copy the result into the next tool.
Use case: Check whether an L*a*b* value you were given matches the hexadecimal original. Edit either side and compare the updated color and swatch.
Use case: Prepare hexadecimal color snippets for documentation, a ticket, or a commit message. Copy the ready-to-paste CSS line when you need a code-friendly value.
Use case: Sanity-check a color conversion before pasting the result into code. The swatch and out-of-gamut warning help you review the displayed color.
Use case: Compare a color in HEX and LAB while discussing a design or implementation. Seeing both values update live helps keep the two representations aligned.
Use case: Use a color written as RGB notation or a named color as input when you need to inspect its HEX and LAB representations.
