How to Use the Color Converter

Enter a HEX code, adjust the individual red, green, and blue sliders, or pick a color visually using the built-in swatch — all three formats (HEX, RGB, HSL) stay in sync automatically, updating instantly no matter which one you edit.

The tool is built so you can work in whichever format is most natural for the task, without manually converting between them.

Choosing your starting format

As covered in the HEX-vs-RGB-vs-HSL guide, start from whichever format you already have the color in — a HEX code from a brand guideline, individual RGB values from a design file, or the color picker if you're starting from scratch and just want to explore visually.

Copying the result for your project

Use the copy button next to any of the three formats to grab a ready-to-paste CSS value — as covered in the HSL-for-design guide, converting to HSL first is especially useful if you're about to generate a lighter or darker variant of the color for your project.

Frequently asked questions

Can I use my system's native color picker instead of typing a HEX code?

Yes — the color swatch opens your device's own color picker, letting you choose visually rather than typing exact numbers, with the result feeding back into all three formats automatically.

Will the color I see in the tool match exactly what I see elsewhere?

As covered in the different-screens guide, minor variation between devices and displays is normal and expected — the numeric HEX, RGB, and HSL values themselves are exact and consistent regardless of how any individual screen renders them.
