What Are Hex Codes Colors?

Hex codes colors (hexadecimal color codes) are a standardized way of representing colors in web design, digital art, and programming. They provide a precise and universal method to define specific colors for use in HTML, CSS, and other applications.

Each hex color code starts with a hash symbol (#) followed by six hexadecimal digits. These six digits represent the red, green, and blue components of a color, each ranging from 00 to FF in hexadecimal notation (0-255 in decimal).

Hex Code Structure:

#RRGGBB
RR
GG
BB

RR: Red value (00-FF)
GG: Green value (00-FF)
BB: Blue value (00-FF)

Primary Colors in Hex

#FF0000

Pure Green

#00FF00

Note: By mixing these primary colors in different proportions, you can create any of the 16,777,216 colors possible in the RGB color space.

How to Use Hex Codes in Web Development

Using Hex Codes in CSS

/* CSS color properties using hex codes */
body {
  background-color: #F9F9F9;
}

h1, h2, h3 {
  color: #333333;
}

.button-primary {
  background-color: #4285F4;
  color: #FFFFFF;
  border: 1px solid #2979FF;
}

.alert {
  color: #D32F2F;
  border-left: 4px solid #F44336;
  background-color: #FFEBEE;
}

CSS Properties That Accept Hex Colors:

  • color
  • background-color
  • border-color
  • outline-color
  • box-shadow
  • text-shadow

Using Hex Codes in HTML

<!-- Inline styles using hex color codes -->
<p style="color: #2196F3;">
  This text is blue
</p>

<div style="background-color: #F5F5F5;
            border: 1px solid #DDDDDD;
            padding: 15px;">
  This div has a light gray background
  with a darker gray border
</div>

<span style="color: #4CAF50; 
             font-weight: bold;">
  This text is green and bold
</span>

Best Practices for Using Hex Colors:

  • Use CSS variables to maintain consistent colors throughout your site:

:root {
  --primary-color: #4285F4;
  --secondary-color: #34A853;
  --text-color: #333333;
}

.button {
  background-color: var(--primary-color);
  color: white;
}
  • Ensure accessibility by maintaining sufficient contrast between text and background colors (WCAG recommends at least 4.5:1 ratio).

  • Use shorthand hex when possible: #RGB instead of #RRGGBB when each pair has identical digits (e.g., #F00 instead of #FF0000).

Advanced Hex Code Features

8-digit Hex Codes for Transparency

Modern browsers support 8-digit hex codes where the last two digits represent the alpha (transparency) channel:

#RRGGBBAA

Example: #FF000080 is red with 50% opacity (80 in hex is 128 in decimal, which is 50% of 255).

CSS Color Functions with Hex

You can use CSS color functions with hex codes:

color: color-mix(in srgb, #FF0000, #0000FF 50%);

This mixes red and blue to create purple.

Hex Code Tips and Tricks

Shorthand Hex Codes

If each channel has repeated digits, you can use a 3-digit shorthand hex code. For example, #FF0000 can be written as #F00.

Color Manipulation Techniques

Darkening a Color

To darken a color, decrease the values of all three channels proportionally.

Lightening a Color

To lighten a color, increase the values of all three channels proportionally.

Creating Transparency

For transparency, use 8-digit hex codes or RGBA:

#4285F480 (50% opacity)
rgba(66, 133, 244, 0.5) (equivalent)

Accessibility with Hex Colors

When using hex colors for text and backgrounds, ensure sufficient contrast for readability. The Web Content Accessibility Guidelines (WCAG) recommend:

  • Minimum contrast ratio of 4.5:1 for normal text

  • Minimum contrast ratio of 3:1 for large text (18pt+) or bold text (14pt+)

Good Contrast✓ Accessible

White text (#FFFFFF) on blue (#1976D2)

Contrast ratio: 6.4:1

Poor Contrast✗ Not Accessible

Light blue text (#4FC3F7) on blue (#BBDEFB)

Contrast ratio: 1.4:1

Frequently Asked Questions

How do hex codes represent colors?

Hex codes represent colors by specifying the intensity of red, green, and blue components using hexadecimal values. Each hex code starts with a # symbol followed by six hexadecimal digits (0-9, A-F), where the first two digits represent the red component, the middle two represent the green component, and the last two represent the blue component. Each pair of digits can express values from 0 (00) to 255 (FF) in decimal, giving a total of 16,777,216 possible colors. For example, #FF0000 represents pure red, with maximum red (FF) and no green (00) or blue (00).

What's the difference between hex codes and RGB values?

Hex codes and RGB values both represent the same colors but use different notation systems. Hex codes use a hexadecimal (base-16) system with format #RRGGBB, while RGB uses decimal values in the format rgb(R, G, B). For example, the color blue can be represented as #0000FF in hex or rgb(0, 0, 255) in RGB. The main advantages of hex codes are their compactness and widespread use in web development. RGB format is sometimes preferred when transparency is needed, as it can be extended to rgba() to include an alpha channel for opacity.

How do I find the hex code for a specific color?

There are several ways to find the hex code for a specific color:

1. Use our interactive color picker at the top of this page
2. Use the color picker tool in design software like Photoshop, Figma, or Sketch
3. Use browser developer tools to inspect elements with the color you want
4. Use an eyedropper tool or color picker browser extension to sample colors from any webpage
5. Use our image color extractor tool to pull colors from images
6. Browse our color charts and libraries of named colors

Most of these methods will provide the hex code (and often RGB and HSL values as well) for any color you select.

Are there any standard or "safe" hex colors for web design?

While modern displays can show millions of colors, there are still some standard color systems used in web design:

1. Web Safe Colors: A historical palette of 216 colors (using combinations of 00, 33, 66, 99, CC, and FF) designed to display consistently across older browsers. While less relevant today, some designers still use them for retro designs or maximum compatibility.

2. Material Design Colors: Google's design system includes a specific color palette with primary colors and various shades. These colors are widely used in modern web applications and have well-established hex codes.

3. Brand Colors: Many major brands have established specific hex codes for their brand colors that have become recognizable standards (like Facebook blue #3b5998 or Twitter blue #1DA1F2).

In general, modern web design isn't restricted to any specific color set, but using established color systems can help create a more cohesive and professional appearance.
