Rgb Hex Converter
Convert units with the Rgb Hex Converter — enter a value and get accurate converted results instantly using verified formulas.
Formula
Hex = #(R_hex)(G_hex)(B_hex)
Each RGB decimal value (0-255) is converted to its two-digit hexadecimal equivalent (00-FF) and concatenated with a hash prefix. The reverse conversion parses each hex pair back to decimal.
Worked Examples
Example 1: Converting a Brand Color to Hex
Problem: Convert the RGB color (41, 128, 185) to its hexadecimal representation for use in a website stylesheet.
Solution: Red: 41 / 16 = 2 remainder 9, so 41 = 29 in hex\nGreen: 128 / 16 = 8 remainder 0, so 128 = 80 in hex\nBlue: 185 / 16 = 11 remainder 9, so 185 = B9 in hex\nHex Code = #2980B9\nLuminance = 0.2126(0.161) + 0.7152(0.502) + 0.0722(0.725) = 0.446
Result: Hex: #2980B9 | HSL: 204deg 64% 44% | Luminance: 0.446
Example 2: Converting Hex to RGB
Problem: Convert the hex color #E74C3C to its RGB values for use in a design tool that requires decimal input.
Solution: E7 in decimal = 14x16 + 7 = 231\n4C in decimal = 4x16 + 12 = 76\n3C in decimal = 3x16 + 12 = 60\nRGB = (231, 76, 60)\nThis is a vibrant red/coral color
Result: RGB: (231, 76, 60) | HSL: 6deg 78% 57% | Brightness: 42.1%
Frequently Asked Questions
What is the difference between RGB and Hex color codes?
RGB and Hex are two different notations for representing the exact same colors. RGB uses three decimal numbers ranging from 0 to 255 for the red, green, and blue channels, written as rgb(255, 128, 0) in CSS. Hex uses a six-character hexadecimal string prefixed with a hash symbol, where each pair of characters represents one color channel in base-16 notation, such as #FF8000. The conversion is straightforward because each hex pair directly corresponds to one RGB channel. FF in hexadecimal equals 255 in decimal, 80 equals 128, and 00 equals 0. Both formats can represent exactly 16,777,216 unique colors, which is 256 cubed. Hex notation is more compact and is the traditional format used in web development and design.
How do you manually convert RGB values to hexadecimal?
Converting RGB to hexadecimal requires converting each decimal value from 0 to 255 into its two-digit hexadecimal equivalent. To convert a decimal number to hex, divide the number by 16 to get the first digit, and the remainder becomes the second digit. Each digit maps to the hex characters 0-9 and A-F, where A=10, B=11, C=12, D=13, E=14, and F=15. For example, to convert RGB value 200 to hex: 200 divided by 16 equals 12 remainder 8, so 200 decimal equals C8 in hex. For the full color rgb(66, 133, 244): 66 becomes 42, 133 becomes 85, and 244 becomes F4, giving the hex code #4285F4. Single-digit hex values are padded with a leading zero.
What are shorthand hex codes and when can you use them?
Shorthand hex codes use three characters instead of six to represent colors in a more compact form. This shorthand is only valid when each pair of hexadecimal digits in the full code consists of two identical characters. For example, #FF5533 can be shortened to #F53, where each character is doubled to reconstruct the original: F becomes FF, 5 becomes 55, and 3 becomes 33. Common shorthand codes include #FFF for white, #000 for black, #F00 for red, #0F0 for green, and #00F for blue. However, most real-world colors cannot use shorthand because their hex pairs are not made of identical characters. The code #4285F4 cannot be shortened because 42, 85, and F4 do not have repeating characters. Modern CSS also supports eight-digit hex codes with alpha transparency.
How do HSL and HSV color models relate to RGB and Hex?
HSL and HSV are alternative color models that represent the same colors as RGB and Hex but organize them in a more intuitive way for humans. HSL stands for Hue, Saturation, and Lightness, while HSV stands for Hue, Saturation, and Value. The hue component ranges from 0 to 360 degrees on a color wheel, where 0 is red, 120 is green, and 240 is blue. Saturation represents color intensity from 0 percent being gray to 100 percent being full color. In HSL, lightness goes from 0 percent being black to 100 percent being white with 50 percent being the pure color. HSV is similar but value represents brightness from 0 being black to 100 being the brightest. Designers often prefer HSL for adjusting colors because changing lightness or saturation independently is more intuitive than modifying individual RGB channels.
