Color manipulation is a common requirement in web development, graphic design, and data visualization. Designers and developers often work with different color formats such as HEX, RGB, and RGBA. Converting these values programmatically helps in generating dynamic styles, themes, and graphics. In this article, we will learn how to convert HEX to RGB or HEX to RGBA color codes in Python.

Why Convert HEX to RGB or RGBA?

Before diving into code, let’s understand the need for such conversions:

  • HEX format (#RRGGBB) is widely used in web design and CSS styling.
  • RGB format (rgb(red, green, blue)) expresses colors with explicit numerical values between 0 and 255.
  • RGBA format (rgba(red, green, blue, alpha)) extends RGB by adding transparency through the alpha channel (0 to 1).

When working with SVGs, images, or CSS styles programmatically, converting between these formats ensures better compatibility and easier styling.

Python Library to Convert HEX to RGB or RGBA

Aspose.SVG for Python via .NET is a high-performance library that provides advanced APIs for SVG parsing, rendering, and manipulation. It also offers convenient classes for handling colors and CSS values, which makes color conversion tasks efficient.

With Aspose.SVG for Python, you can:

  • Parse and manipulate SVG files.
  • Handle CSS styles, including colors in HEX, RGB, and RGBA.
  • Convert colors between different formats in Python.

You can simply install the package using pip:

pip install aspose-svg-net

You may also download Aspose.SVG for Python from the releases.

Convert HEX to RGB in Python

In this section, we will see how to parse a HEX color code and convert it into its RGB equivalent.

Follow the steps below to convert HEX to RGB:

  1. Import necessary classes from Aspose.SVG.
  2. Create a Color object using the from_string() method with HEX string.
  3. Convert HEX to RGB using the to_rgb_string() method.
  4. Print or use the RGB values.

The following code example shows how to convert HEX to RGB in Python:

Output:

HEX #DEB487 → RGB: rgb(222, 180, 135)

Convert HEX to RGBA in Python

Sometimes, you may need to add transparency to your colors. This is where RGBA format is used. The alpha value ranges from 0.0 (fully transparent) to 1.0 (fully opaque).

Follow the steps below to convert HEX to RGBA:

  1. Import necessary classes.
  2. Create a color object from the HEX string.
  3. Convert HEX value to RGBA using the to_rgba_string() method.
  4. Construct the RGBA representation.

The following code example shows how to convert HEX to RGBA in Python:

Output:

HEX #DEB487 → RGBA: rgba(222, 180, 135, 1)

Applying Converted Colors to SVG

Once converted, these RGB or RGBA values can be directly applied to SVG shapes or styles using Aspose.SVG.

Follow the steps below to apply color in SVG using Python:

  1. Create a new SVG document.
  2. Access the root element using the root_element property of the document.
  3. Create a rectangle element with the create_element_ns() method.
  4. Set position and size using the set_attribute() method.
  5. Apply fill color using the fill attribute with your RGBA color code.
  6. Insert the rectangle inside the root element.
  7. Save the SVG document using the save() method.

The following code example shows how to apply a converted RGBA color code in the SVG using Python:
