Color Picker Online — Pick Colors and Get HEX, RGB, HSL Values

You need a specific color for your design or CSS but you are not sure of the exact code. The Color Picker lets you select any color visually and instantly gives you the HEX, RGB, and HSL values — ready to copy into your code or design tool.

How to Use the Color Picker

1. Go to rohansurve.in/free-tools/color-picker
2. Click anywhere on the color spectrum to select a color
3. Adjust hue, saturation, and brightness as needed
4. Get HEX, RGB, and HSL values instantly
5. Copy the format you need

You can also type a known HEX code and get the RGB and HSL equivalents immediately.

HEX vs RGB vs HSL — Which Format to Use

HEX — #6366F1 — the standard format for CSS and most design tools. Six characters representing red, green, and blue in hexadecimal. This is what you paste into Tailwind classes, CSS files, and Figma color fields.

RGB — rgb(99, 102, 241) — red, green, blue as decimal values from 0 to 255. Useful in CSS when you need to use the rgba() function to add transparency: rgba(99, 102, 241, 0.5).

HSL — hsl(239, 84%, 67%) — hue, saturation, lightness. The most intuitive format for creating color variations. To make a color lighter, increase lightness. To make it less saturated, decrease saturation. HSL makes color systems much easier to build consistently.

Building a Color Palette That Works

Picking one color is easy — building a set that looks intentional is the harder part. A reliable shortcut is to lock the hue and vary only lightness in HSL. Take your base color, then create a lighter tint and a darker shade by moving lightness up and down by 10–15% while keeping hue and saturation fixed. You get a cohesive palette without guessing.

For accent colors, shift the hue by 30–60 degrees from your primary to land on a complementary or analogous match that still feels related to the base.

Checking Contrast for Accessibility

A color that looks good is not always readable. Text needs enough contrast against its background to meet WCAG guidelines — a ratio of at least 4.5:1 for normal body text and 3:1 for large text. Light grey text on a white card may look elegant but fail for many readers.

When you pick a text color and a background color, check the pair against these ratios before shipping. Dark text on light backgrounds (and the reverse) is almost always safe; mid-tone on mid-tone is where contrast usually breaks.

Common Color Code Mistakes

• Wrong HEX length — #FFF is valid shorthand for #FFFFFF, but #FFFF is not. Stick to 3 or 6 digits.
• RGB out of range — each channel maxes out at 255. rgb(300, 0, 0) is invalid and clamps unpredictably.
• Forgetting alpha — rgb() has no transparency; use rgba() or an 8-digit HEX like #6366F180 when you need it.
