What is a Hex Color Code?

A hex color code (hexadecimal color) is a 6-digit code used to represent colors in web design, CSS, and digital graphics. The code consists of three pairs of hexadecimal digits (0-9 and A-F) that represent the intensity of red, green, and blue components. Each pair ranges from 00 (minimum, 0) to FF (maximum, 255).

For example, #FF5733 breaks down as:

• FF = 255 Red (maximum red intensity)
• 57 = 87 Green (moderate green intensity)
• 33 = 51 Blue (low blue intensity)

The result is a vibrant coral-orange color. The # symbol is optional but commonly included to identify the value as a hex color code.

3-Digit Shorthand

When all three color pairs use repeated digits, you can use the 3-digit shorthand. For example, #FF5533 cannot be shortened, but #FFAA00 can be written as #FA0. Each digit is automatically doubled: F becomes FF, A becomes AA, 0 becomes 00.

How to Convert Hex to RGB

Converting hex to RGB involves converting each pair of hexadecimal digits to its decimal equivalent:

1. Remove the # symbol if present
2. Split into pairs: Divide the 6 digits into 3 pairs (RR, GG, BB)
3. Convert each pair: Convert from base-16 (hexadecimal) to base-10 (decimal)

Hex to Decimal Conversion

Each hex digit position has a value: the first digit is multiplied by 16, and the second digit is added. For hex pair "5A":

5 × 16 + 10 (A) = 80 + 10 = 90

Understanding Color Formats

RGB and RGBA

RGB (Red, Green, Blue) uses three values from 0-255 to define a color. RGBA adds an Alpha channel (0 to 1) for transparency. RGB(255, 87, 51) is solid, while RGBA(255, 87, 51, 0.5) is 50% transparent.

HSL and HSLA

HSL (Hue, Saturation, Lightness) is often more intuitive for designers:

• Hue: Color wheel position (0-360 degrees). 0=red, 120=green, 240=blue
• Saturation: Color intensity (0-100%). 0% is gray, 100% is vivid
• Lightness: Brightness (0-100%). 0% is black, 100% is white, 50% is pure color

CMYK

CMYK (Cyan, Magenta, Yellow, Key/Black) is used for print production. While screens use additive color mixing (RGB), printers use subtractive mixing (CMYK). Colors may appear differently when printed, so checking CMYK values helps ensure accurate print reproduction.

Color Theory: Complementary and Triadic Colors

Complementary Colors

Complementary colors sit opposite each other on the color wheel, creating maximum contrast. The colour-wheel complement is found by rotating the hue 180° at the same saturation and lightness. Subtracting each RGB channel from 255 gives the RGB inverse (negative), not the colour-wheel complement; see /color-inverter/ for the difference. Complementary pairs are used for:

• Call-to-action buttons that stand out
• Logo designs with visual impact
• Creating visual tension and energy

Triadic Colors

Triadic colors are three colors equally spaced on the color wheel (120 degrees apart). They create vibrant, balanced palettes that maintain harmony while offering variety. This scheme is popular in graphic design and branding.

WCAG Accessibility and Contrast

The Web Content Accessibility Guidelines (WCAG) define contrast ratios for readable text:

• Level AAA (7:1): Excellent - highest accessibility standard
• Level AA (4.5:1): Good - minimum for normal text
• Level AA Large (3:1): Acceptable for large text (18pt+ or 14pt bold)
• Fail (<3:1): Insufficient contrast for accessibility

Our tool calculates contrast ratios against both white and black backgrounds, helping you choose accessible text colors for your designs.

How to Use This Converter

1. Enter your hex code: Type or paste a hex color (with or without #). Both 6-digit and 3-digit formats work.
2. Set alpha (optional): Adjust transparency from 0 (invisible) to 1 (solid) for RGBA/HSLA output.
3. Click Convert: Instantly see RGB, HSL, CMYK values and color preview.
4. Copy any format: Click the copy button to copy values to your clipboard.
5. Explore palettes: View complementary colors, triadic schemes, shades, and tints for design inspiration.

Frequently Asked Questions

What is a hex color code?

A hex color code is a 6-digit (or 3-digit shorthand) hexadecimal representation of a color used in web design and digital graphics. It starts with a # symbol followed by six characters (0-9 and A-F) representing the red, green, and blue components. For example, #FF5733 represents a coral-orange color with Red=255, Green=87, Blue=51.

How do I convert hex to RGB?

To convert hex to RGB manually: 1) Remove the # symbol, 2) Split the 6 digits into 3 pairs (RR, GG, BB), 3) Convert each pair from hexadecimal to decimal. For example, #FF5733: FF=255 (red), 57=87 (green), 33=51 (blue), giving RGB(255, 87, 51). Our converter does this instantly.

What is the difference between RGB and RGBA?

RGB specifies color using Red, Green, and Blue values (0-255 each). RGBA adds an Alpha channel (0-1) for transparency. RGB(255, 87, 51) is a solid color, while RGBA(255, 87, 51, 0.5) is the same color at 50% opacity. RGBA is essential for creating semi-transparent overlays and effects.

What is HSL color format?

HSL stands for Hue, Saturation, and Lightness. Hue is the color angle (0-360 degrees), Saturation is color intensity (0-100%), and Lightness is brightness (0-100%). HSL is often more intuitive for designers because adjusting lightness or saturation is straightforward without affecting the base hue.

What is CMYK and when should I use it?

CMYK stands for Cyan, Magenta, Yellow, and Key (Black). It is the color model used in print production. While hex and RGB are for screens (additive color), CMYK is for printing (subtractive color). If your design will be printed, you should check the CMYK values to ensure color accuracy.

What is a complementary color?

A complementary color is the color directly opposite another on the color wheel, creating maximum contrast. The colour-wheel complement is found by rotating the hue 180° at the same saturation and lightness. Inverting the RGB values (255 minus each channel) gives the RGB inverse (negative), not the colour-wheel complement; see /color-inverter/ for the difference. Complementary colors create vibrant, high-contrast designs and are commonly used in logos and call-to-action elements.
