Color Picker / HEX RGB Converter
Convert colors between HEX, RGB, HSL formats and pick colors visually.
Convert colors between HEX, RGB, and HSL formats, and preview any color visually — useful for web design, CSS, and graphic design work.
How Color Picker / HEX RGB Converter Works
HEX color codes represent a color as three pairs of hexadecimal digits (00-FF), one pair each for red, green, and blue intensity. The calculator converts a HEX code to RGB by reading each pair as a base-16 number from 0 to 255, or converts RGB values back to HEX the same way in reverse.
HSL (hue, saturation, lightness) describes color differently — as a position on a color wheel (hue, 0-360°), how vivid the color is (saturation, 0-100%), and how light or dark it is (lightness, 0-100%). The calculator derives HSL from the RGB values using the standard RGB-to-HSL conversion formula, which finds the lightness from the average of the highest and lowest RGB channels and derives hue from which channel is dominant.
A live color swatch preview is shown alongside the numeric values so you can visually confirm the color looks right before using it in your design.

Who Uses Color Picker / HEX RGB Converter and Why
- Converting a HEX color code from a design file into RGB values needed for a specific piece of code or software.
- Finding the HSL equivalent of a brand color to create lighter or darker shades while keeping the same hue.
- Checking exactly what color a HEX code represents before using it in a website's CSS.
- Translating a color between formats when moving assets between tools that expect different color notations.
Mistakes to Avoid
- Assuming HEX, RGB, and HSL are visually different color systems rather than three ways of describing the exact same color — converting between them never changes the actual color, only how it's written.
- Manually adjusting individual RGB values to make a color lighter or darker — this shifts the hue slightly in most cases; adjusting the lightness value in HSL instead keeps the hue and saturation untouched.
- Forgetting that a HEX code needs all six digits (or a valid 3-digit shorthand) — an incomplete or malformed HEX string won't convert correctly.
Tips for Best Results
- Use HSL when you need a family of matching shades of the same color — adjust only the lightness value to get lighter or darker variants while the hue and saturation stay consistent.
- All three formats — HEX, RGB, and HSL — are accepted equally by modern CSS, so pick whichever is easiest for you to read and edit rather than worrying about compatibility.
Fixing Common Problems
The RGB values don't match the HEX code I expected. — Double-check the HEX code was entered correctly with all 6 digits (or a valid 3-digit shorthand) — a typo in even one digit changes the resulting RGB values.
A color looks different on screen than the values suggest it should. — Display calibration and screen brightness vary between monitors, so the same RGB or HEX value can appear slightly different across devices — the numeric values themselves are exact even if the visual rendering isn't identical everywhere.
Terms Explained
HEX: A six-digit hexadecimal code representing a color's red, green, and blue components packed into a single compact string, commonly used in web design.
HSL (Hue, Saturation, Lightness): A color model describing a color by its base hue, how saturated (vivid) it is, and how light or dark it is — often more intuitive for creating shade variants than RGB.
RGB: A color model specifying red, green, and blue intensity, each on a 0-255 scale, that combine to produce the final color.
