More than a basic RGB converter

The tool keeps related color representations together so you can move from visual selection to implementation without opening multiple utilities.

Visual and numeric input

Pick visually, paste a color string, enter exact channel values or adjust sliders for fast and precise control.

Multiple color formats

Convert one selection to HEX, RGB(A), HSL(A), HSV, CMYK and a ready-to-copy CSS custom property.

Text contrast check

Compare the selected color with white and dark text, including contrast ratios and an AA threshold indicator.

One-click copying

Copy a single code or copy every generated format at once, with clear success feedback.

Accessible controls

Labeled inputs, visible focus states and keyboard-operable buttons make the picker practical without a mouse.

Private and immediate

Conversions run locally, so there is no server round trip for ordinary color calculations.

How it works

From a color idea to usable code in three steps

01 / SELECT

Choose or enter a color

Use the native picker, paste HEX/RGB/HSL notation, or set red, green and blue channels directly.

02 / CONVERT

Review equivalent formats

The tool recalculates RGB, HEX, HSL, HSV and CMYK values as the selected color changes.

03 / USE

Copy, check or export

Copy the format your project needs, compare text contrast or download the current color as JSON.

Practical tips

Get more reliable results from your color choices

Use exact RGB channels for handoff

When a specification already gives numeric RGB values, enter them directly instead of matching by eye.

Check contrast in context

The built-in ratio is a useful screening check, but final accessibility depends on actual text size, weight and background.

Keep alpha separate when needed

Opacity changes the final composited color, so preserve the alpha channel when matching translucent interface elements.

Prefer HEX or RGB for exact web matching

HEX and RGB directly encode screen channels and are easy to transfer between code and many design tools.

FAQ

Common RGB color picker questions

What is an RGB color picker?

An RGB color picker is a tool for choosing a color and seeing the red, green and blue channel values that create it. This picker also converts the same color to HEX, HSL, HSV and CMYK-style values.

What range do RGB values use?

Standard 8-bit RGB uses values from 0 to 255 for red, green and blue. For example, rgb(255, 0, 0) is pure red, while rgb(0, 0, 0) is black.

Can I enter a HEX or HSL color instead of RGB?

Yes. You can paste common HEX, RGB/RGBA or HSL/HSLA color strings into the color field. The tool validates the value and updates all supported formats.

What is the difference between RGB and HEX?

RGB describes a color with three numeric channels. HEX encodes those same channel values in hexadecimal notation, such as #3B82F6. Both commonly represent colors on screens and the web.

What does the alpha value do?

Alpha controls opacity. A value of 1 is fully opaque and 0 is fully transparent. When alpha is below 1, the picker also shows RGBA, HSLA and 8-digit HEX output where relevant.

How does the contrast check work?

The tool compares the selected color with white and dark text using relative luminance and contrast ratio calculations. It highlights whether the stronger pairing reaches the common 4.5:1 WCAG AA threshold for normal text.

Is my color data uploaded anywhere?

No. Color conversion, contrast calculations, recent color history and JSON export run in your browser. Recent colors are stored only in local browser storage when available.

Can I use the generated color codes in CSS?

Yes. Copy the RGB, HEX, HSL or CSS custom property output and paste it into your stylesheet. The CSS variable output is formatted as a ready-to-use custom property declaration.

Need a color code right now?

Jump back to the picker, choose a color and copy the format you need.
