Convert Hex To RGB In Python

Last updated June 8, 2023 by Jarvis Silva In this tutorial I will show you the python program to convert Hex to RGB color code, Hex is a color code format which uses hexadecimal values to indicate a color whereas RGB is another color code which stands for red, green and blue. I hope you understood what RGB and Hex are. Now let’s see how to convert a Hex color code to RGB color code in python.

Python Code To Convert Hex To RGB Color

 hex = input('Enter HEX value: ').lstrip('#') print('RGB value =', tuple(int(hex[i:i+2], 16) for i in (0, 2, 4))) 

• The code prompts the user to enter a HEX value using the input() function.
• The entered HEX value is stored in the variable hex .
• The lstrip(‘#’) function is used to remove any leading ‘#’ character from the input, allowing the code to handle both ‘#FFFFFF’ and ‘FFFFFF’ formats.
• The tuple(int(hex[i:i+2], 16) for i in (0, 2, 4)) expression converts the HEX value to RGB.
  • It splits the HEX value into three 2-character segments (representing the red, green, and blue components).
  • For each segment, int(hex[i:i+2], 16) converts the segment to an integer using base 16 (hexadecimal).
  • The resulting RGB values are collected as a tuple.

  Now you can run this code to run this program you need to have python installed, if you don’t have, then read this: Install and setup python or else use this online python compiler, after running the program, you will see your given Hex code to an RGB Color Code like below.

   Enter HEX value: #eeeeee RGB value = (238, 238, 238) 

  As you can see, we have successfully converted Hex Color to RGB color, I hope you found this program helpful, want to know how to convert RGB to Hex color code then read this tutorial: Convert RGB To Hex In Python.

  Convert HEX to RGB and HSV in Python

  The three-color models are RGB, HSV, and HEX. RGB stands for Red, Green, and Blue. HSV stands for Hue, Saturation, and Value. HEX is a hexadecimal representation of RGB values.

  RGB is the most common color model in web design because it is the most intuitive to work with on a computer monitor. It is also the easiest to convert from one format to another such as from HEX or HSV values.

  HSV is an alternative to RGB that can be used in web design for coloring text or backgrounds because it has a greater range than RGB does. It also has more intuitive controls than RGB does for adjusting colors on a monitor.

  HEX values are often used when specifying colors in HTML because they are easier to type than decimals.

  HEX to RGB

  RGB color channel is an additive color model in which red, green, and blue colors are added together to create a varied range of colors. The three colors in the mix are each represented with an 8-bit signed integer – an integer between 0 and 255.

  For example, RGB(255, 0, 0) represents the red color, RGB (0, 0, 255) is blue, and mixing all the three colors at full intensity, that is, RGB (255, 255, 255) gives a white.

  On the other hand, HEX color space is a hexadecimal representation of 8-bit signed RGB color. To understand the conversion of HEX to RGB, therefore, we need to cover the conversion of hexadecimal into decimal.

  Hexadecimal to Decimal Conversion

  Hexadecimal or simply hex contains 16 units – numbers 0-9 and letters A through F. That means hex place values are of powers of 16.

  

  Since HEX place values are to the powers of 16, we convert HEX into RGB by simply taking each place value with a unit and adding them together.

  Let us work on an example of converting HEX values to RGB equivalent.

  HEX(#180C27) to RGB?

  

  Hue is measured in degrees ranging from 0 to 360 and represents the color model of the channel, saturation, and value ranging from 0 to 100 percent explaining the amount of gray component and the intensity of color, respectively.

  Since we already know HEX->RGB, to understand HEX->HSV, we will discuss how RGB is converted to HSV.

  RGB to HSV

  This conversion can be achieved using the following steps

  1. Normalize r,g,b values by dividing them by 255.
  2. Compute max(r,g,b), min(r,g,b), and the difference between the two.
  3. Calculate H.
     • if max(r,g,b)=,min(r,g,b)=0, then H = 0
     • if max(r,g,b)=r, then, H = (60 * ((g – b) / difference ) + 360) % 360
     • if max(r,g,b)=g, then, H= (60 * ((b – r) / difference) + 120) % 360
     • if max(r,g,b)=b, then, H = (60 * ((r – g) / difference) + 240) % 360
  4. Calculate S :
     • if max(r,g,b)= 0, then, S = 0
     • if max(r,g,b)!=0 then, S = (difference/max(r,g,b))*100
  5. Lastly, compute V :
     • v = max(r,g,b)*100

  Let’s put these steps into Python code.

  HTML colors to/from RGB tuples (Python recipe) by Paul Winkler

  You have colors in a number of formats (html-style #RRGGBB, rgb-tuples (r, g, b), and PIL-style integers). You want to convert between formats. It’s pretty easy to do, but also pretty easy to forget; hence, this recipe.

  Just for kicks, we’ll extract an RGB tuple from an image file at the end.

  In C, I probably would have done some bit-shifting and masking. Of course you could do that in python, but I’ve been shielded from bit-twiddling so long, I found it easier to use hex strings 🙂

  Note that PIL integer colors have red as the least-significant byte, not the most.
