Best Online Color Converter Tools

I am a big fan of online color tools, because they are handy and fast! The more user-friendly they are, the more excited I feel. Today, I will explore 7 Best Online Color Converter Tools in 2021 you’ll find anywhere! So, read on!

Different Color Models

A color model is a way to define a specific color in different systems. As an example, there are more than 16 million colors in the digital world. Then, how do you think designers address them to distinguish each? The RGB color system is one of the popular color models. However, is that the only one? Not at all, there are more than ten color systems in the world right now! Let me introduce popular color systems now!

  • Hex: Three byte hexadecimal numbers (meaning they consist of six digits), with each byte, or pair of characters in the Hex code, representing the intensity of red, green and blue in the color respectively. The code bytes ranges is from 00 (the lowest) to ff (the highest).
  • CMYK: CMYK color stands for cyan (C), magenta (M), yellow (Y), and black (K for “key”), varies from 0 to 100. To give an example, commercial printing equipment use this color mode to create full-color graphics and images. 
  • RGB: It stands for Red, Green, and Blue. Hence, they are the three hues of light that can be mixed together to create different colors. Each color code ranges is from 0 to 255 in a RGB color model.
  • Lab Color: The LAB color model is based on how much color there is on the green to red axis combined with how much color there is on the blue to yellow axis, combined with a lightness value from light to dark. You can see a diagram here to understand it!
  • PMS: Pantone is a company that specializes in products that accommodate color matching, called the Pantone Matching System, or PMS for short.
  • HSB: It stands for hue, saturation, and brightness. HSB is an intuitive and user-friendly way to mix custom colors and create the nearest to the one that is in your mind, and you have no idea how it s represented in other models.
  • NCol: Natural colors (NCol) is an initiative from W3Schools. The system is designed to make it easier to select HTML colorsNCol specifies colors using a color letter with a number to specify the distance (in percent) from the color. R30 means 30% away from Red , moving towards Yellow.
