Convert between RGB color values and hexadecimal color codes. Essential for web development, design, and digital color work.
Last updated: March 2026 | By Patchworkr Team
RGB and HEX are two different ways to represent the same colors in digital design. RGB (Red, Green, Blue) uses three numbers from 0-255 to specify how much red, green, and blue light to mix. For example, RGB(255, 0, 0) is pure red, RGB(0, 255, 0) is pure green, and RGB(255, 255, 255) is white.
HEX (hexadecimal) codes represent the same color information but use base-16 notation. A HEX color starts with # followed by 6 characters (or 3 as shorthand). Each pair of characters represents the red, green, and blue values: #RRGGBB. For example, #FF0000 is red, #00FF00 is green, and #FFFFFF is white. Each pair ranges from 00 (0 in decimal) to FF (255 in decimal).
Both formats are widely used in web development and design. CSS accepts both rgb(255, 100, 50) and #FF6432. HEX codes are more compact and traditional for web colors, while RGB is often more intuitive for humans and easier to manipulate programmatically. Understanding both is essential for modern web development.
Converting RGB(255, 100, 50) to HEX:
RGB(255, 100, 50) converts to #FF6432, a vibrant orange-red color.
RGB uses decimal numbers (0-255) for each color channel, while HEX uses hexadecimal notation (00-FF). They represent the exact same colors—just different notation. RGB(255, 0, 0) = #FF0000 (red).
Yes! #RGB is shorthand for #RRGGBB. Each character is duplicated: #F0A becomes #FF00AA. This only works when each color pair has identical digits. Not all colors have a 3-character shorthand.
The # symbol is just a prefix that indicates 'this is a hexadecimal color code.' It's required in CSS and HTML but not part of the actual color value. #FF0000 and FF0000 represent the same color.
Hexadecimal is more compact (6 characters vs 12+ for RGB) and maps directly to how computers store colors in memory (each byte = 2 hex digits). It's traditional in web development and easier to type.
Black is RGB(0, 0, 0) or #000000 (often shortened to #000). White is RGB(255, 255, 255) or #FFFFFF (or #FFF). These are the extremes of the color spectrum.
No, the standard RGB color model uses 8 bits per channel, which can only represent 0-255 (256 values). Values are clamped: numbers above 255 become 255, below 0 become 0.
Both can represent 16,777,216 colors (256³). Each of the three channels (R, G, B) has 256 possible values, so 256 × 256 × 256 = 16.7 million unique colors.
RGBA adds an alpha channel for transparency (0-1 or 0-255). HEX can use 8 characters (#RRGGBBAA) for transparency, though the 6-character version is more common. This converter focuses on opaque colors.
