If red, green, and blue are all at the maximum 255 (represented as “ff” in the code), the color expressed is the color white. If red, green, and blue are all at the minimum 0 (represented as “00” in the code), the color expressed is the color black. The values are a special code that represents color values from 0 to 255. Hex color codes are values that tell the display how much of a color to show. Having every value be six symbols no matter what, reduces the chance of errors. This could cause confusion for the systems reading the codes but especially among the humans doing the coding. In total, the code could be as few as three digits or as many as nine. Why use the hex code instead of numbers? Because if you used numbers, every red, green, or blue value from 0 to 255 could be one, two, or three possible digits. You can use color pickers or converters to create the code for you.Using the hexadecimal codes, you can show more than 16 million unique colors, which is thought to be more than the human eye can perceive.If you’re just wondering what this all means to you as a designer, there are a couple important things to know: If you’re curious, here’s a good explanation. Why? It’s complicated and has to do with the base 16 numbering system. For example, the RGB code (224, 105, 16) is E06910 in hexadecimal code. The code is written using a formula that turns each value into a unique 2-digit alphanumeric code. Each of the 2-symbol elements expresses a color value from 0 to 255. What Is a Hex Color Code?Ī hex color code is a 6-symbol code made of up to three 2-symbol elements. When you want a web page (or web app) to display a certain color, you tell it the hex code. Hexadecimal colors are the visual language of the web.
