Color Picker from Image – Extract Any Color Instantly
The Color Picker from Image tool lets you extract, analyze, and convert any color into HEX, RGB, and HSL formats instantly. Whether you're a web designer, developer, or digital artist, understanding exact color values is essential for maintaining visual consistency. Simply enter a HEX code or adjust the RGB sliders to get a complete breakdown of any color's properties.
Type a HEX color code to analyze its RGB and HSL values (e.g., #FF5733).
Choose which color format values you want to display.
Manually adjust the Red channel (0–255).
Manually adjust the Green channel (0–255).
Manually adjust the Blue channel (0–255).

How to Use This Calculator
1. Enter a HEX color code in the input field (e.g., #FF5733) or manually adjust the Red, Green, and Blue sliders to select your desired color. 2. Choose your preferred display mode from the dropdown — you can view all color formats at once or focus on a specific one such as HEX, RGB, or HSL. 3. Instantly view the converted HEX, RGB, and HSL values in the results panel below. 4. Note the Hue, Saturation, and Lightness percentages for precise color control in CSS or design tools. 5. Check the Perceived Brightness and Relative Luminance outputs to determine if your color is suitable for accessible text contrast.
Understanding Color Formats
Colors on digital screens are represented in several standardized formats. Each format has its own use case and is supported across different design and development tools. Here are the most common ones:
HEX Color Code
A HEX code is a 6-digit hexadecimal representation of a color, prefixed with a # symbol (e.g., #FF5733). Each pair of digits represents the Red, Green, and Blue channels respectively, with values ranging from 00 (0) to FF (255).
RGB Color Model
RGB stands for Red, Green, Blue. It defines a color by specifying the intensity of each channel on a scale from 0 to 255. For example, rgb(255, 87, 51) mixes full red with moderate green and low blue to produce an orange-red tone. RGB is the native model for screens and monitors.
HSL Color Model
HSL stands for Hue, Saturation, and Lightness. Hue is expressed in degrees (0°–360°), representing the position on the color wheel. Saturation controls the intensity of the color (0% = grey, 100% = vivid). Lightness defines brightness (0% = black, 100% = white). HSL is often preferred by designers because it is more intuitive to adjust.
Relative Luminance and Accessibility
Relative luminance is a WCAG (Web Content Accessibility Guidelines) metric that measures the perceived brightness of a color on a normalized scale from 0 (black) to 1 (white). It is calculated using a linearized version of the RGB channels:
- Luminance = 0.2126 × R + 0.7152 × G + 0.0722 × B (after linearization)
- A contrast ratio of at least 4.5:1 is recommended for normal text
- A contrast ratio of at least 3:1 is recommended for large text
Perceived Brightness (YIQ)
The YIQ formula calculates perceived brightness by weighting RGB channels according to human vision sensitivity: YIQ = (R × 299 + G × 587 + B × 114) / 1000. A YIQ score of 128 or above indicates a light color, while below 128 indicates a dark color. This is commonly used to determine whether white or black text will be more readable on a given background.
Converting Between Color Formats
- HEX to RGB: Parse each two-digit hex pair into a decimal integer (base 16).
- RGB to HEX: Convert each channel to its two-digit hexadecimal equivalent and concatenate.
- RGB to HSL: Normalize channels to 0–1, find max/min, and compute hue, saturation, and lightness from the delta.
