Convert HSLA to RGBA Using C#

Aspose.SVG for .NET API offers a high-speed C# library that you can use for different SVG parsing tasks. One of the API features is easy access to work with several color spaces. The Color class allows you to parse colors (such as RGB, HEX, HSL, HWB, CMYK, NCOL, LCH, OKLCH, LAB, OKLAB) from a string representation and convert them to the desired color space. Colors codes and formats play a crucial role in various fields such as web design, graphic design, photography, art and more. Different tasks may require different color formats, hence the need for color conversion functionality.

Online Color Converter

If you need to convert colors from one color model to another, use our free online tool! It supports various color spaces, including HEX, RGB, CMYK, etc. You simply need to enter the color value for conversion! Click inside the color area to select a color, or enter a color code in the Input text box. You will immediately see other color codes for chosen color in the Output section.

How to convert HSLA to RGBA using C#

If you want to use the conversion functions in your product or programmatically convert HSLA to RGBA, see the C# code example above. Color conversion can be done with a few lines of code:

  1. The Color.FromString(“hsla(31.034, 57%, 70%, 0.2)”) method is used to parse the HSLA color code from its string representation and returns a Color instance.
  2. The color.ToRgbaString() method is used to convert the color from HSLA to RGBA color space.
  3. The result of the RGBA color value is printed to the console using Console.WriteLine(rgbaColor).

Please visit our documentation to learn more about using Aspose.SVG API functions and consider C# examples for the most common SVG processing scenarios. In the documentation article How to Change SVG Color , you can view how to change the color of elements and background in SVG images using Aspose.SVG for .NET library. The article SVG Color takes an in-depth look at how SVG text and shapes can be colorized.

Color Converters are free online web applications that allow you to convert colors between different color codes like RGB, HEX, HSL, HSV, HWB, LAB, CMYK, LCH, XYZ, OKLAB, OKLCH, RGBA, HSLA, etc. on the fly. Color Converters are easy-to-use and work on any browser and operating system. You get the result immediately after entering the color code you need to convert.


1. How can I convert HSLA to RGBA?

Aspose.SVG allows you to convert HSLA to other color formats in any way – online or programmatically. For example, you can convert HSLA in real-time using Online Color Converter that transforms color codes quickly and with high quality. Upload, convert and get the result at once!

2. What other color codes can I convert HSLA to?

You can perform conversions between color models such as RGB, HEX, HSL, HSV, HWB, LAB, CMYK, XYZ, LCH, OKLAB, etc.

3. Why should I convert HSLA?

A color space is a specific organization of colors that is a collection of information and data that declares how a system or device displays color to a user. The color spaces are closely linked to the methods of describing and defining these colors using their respective color codes. For different tasks, different color codes are preferred. For example, RGB colors are for the web and CMYK colors are for print.

4. How many colors can I use in HTML, CSS, and SVG?

If you check the RGB system, you will see that there are 256 different quantity options for each color – red, green, and blue. So, according to the RGB cube model, the number of colors is 256^3 = 16 777 216. If you like working with color names, there are 147 HTML color names that can be used in HTML5, including 17 standard ones. Using HTML4, you can handle 140 color names, including 16 standard colors. The secondary color in HTML5 is orange.

What is HSLA Color?

Similar to RGB/RGBA, HSL has an HSLA mode with support for an alpha channel to specify the color opacity. The HSLA (Hue, Saturation, Lightness, Alpha) color value is specified with hue, saturation, lightness, and alpha, where the alpha parameter specifies the opacity. The alpha parameter is a number between 0.0, meaning “fully transparent”, and 1.0, meaning “fully opaque”. For example, hsla(0, 100%, 50%, 1) is displayed as pure red, hsla(0, 100%, 50%, 0.5) is displayed as red with 50% opacity.

What is RGBA Color?

RGBA (Red, Green, Blue, and Alpha) color values are an extension of RGB color values with an alpha channel that determines the opacity of the color. The alpha parameter is a number between 0.0 and 1.0 that specifies transparency. For example, rgba(255, 0, 0) is displayed as pure red, rgba(255, 0, 0, 0.5) is displayed as red with 50% opacity. For an RGBA value, unlike RGB values, there is no hexadecimal notation.
