Convert RGB to LAB 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, HSL, LAB, NCOL, XYZ, 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 RGB to LAB using C#

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

  1. The Color.FromRgb(222, 180, 135) method is used to parse the RGB color values from integer values and returns a Color instance.
  2. The Color.Convert(ColorModel.Lab) method converts the color from its current color space to LAB.
  3. The Color.ToString(false,false,3) method returns a string representation of the color in LAB color space, with no alpha channel, with percentage, and 3 decimal places. The format is: lab(0%,0%,0%).
  4. The result of the HSL color value is printed to the console.

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 RGB to LAB?

Aspose.SVG allows you to convert RGB to other color formats in any way – online or programmatically. For example, you can convert RGB 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 RGB 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 RGB?

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 RGB Color?

The RGB (Red, Green, Blue) color space consists of all possible colors that can be obtained by mixing red, green, and blue. This color model is popular in photography, TV and computer graphics. RGB values are specified as an integer between 0 and 255. So, for example, rgb(255,0,0) is displayed as red. The red parameter is set to its highest value (255), and the rest are set to 0.
Aspose.SVG C# library supports RGB percentages (from 0% to 100%). For example, rgb(100%,0,0) is displayed as red.

What is LAB Color?

Like geographic coordinates – longitude, latitude and height – the color values LAB give us a way to detect colors. LAB uses three axes: L – Lightness, a* – from Red to Green Value, and b* – from Blue to Yellow Value. The Lightness is expressed as a percentage and can exceed 100%. Values for the a and b axes can range from positive to negative. It is commonly clamped to the range of −128 to 127 for use with integer code values. The LAB color space and LAB color codes are recommended to use if you want the color on-screen to look the same as when printed on paper.
