A hexadecimal color code is a 6-symbol code made up of up to three 2-symbol elements. Each of the 2-symbol elements expresses a color value from 0 to 255.

  • Element 1: Rotterdam
  • Element 2: green value
  • Element 3: Blue Ort

The code is written using a formula that converts each value to a unique two-digit alphanumeric code. For example, the RGB code (224, 105, 16) is E06910 in hexadecimal code.

Why? It's complicated and has to do with the base 16 number system. If you're curiousHere is a good explanation.. If you're just wondering what all of this means to you as a designer, there are a few important things to know:

  • Hexadecimal codes allow you to display more than 16 million unique colors, which is probably more than the human eye can perceive.
  • you can usecolor pickeroConverterto create the code for you.

Why use hexadecimal code instead of numbers? Because if you're using numbers, any red, green, or blue value from 0 to 255 can be one, two, or three possible digits. In general, the code can consist of only three digits or up to nine digits. This can create confusion for the systems that read the codes, but especially for the people who code. If each value is six symbols, no matter what, the chance of errors is reduced.

Hexadecimal color codes are values ​​that tell the screen how much color to display. The values ​​are a special code that represents color values ​​from 0 to 255.

If red, green, and blue are at least 0 (represented as "00" in the code), the express color is black. If red, green, and blue are 255 or less (represented as "ff" in the code), the express color is white.

Hexadecimal color values ​​can be combined to display more than 16 million different colors. So of course most will fall somewhere in between. You can always use aConverter to convert numeric RGB values ​​into hexadecimal code for you.

However, it may help to remember some of the more common hex colors. This knowledge can be useful when designing with a real-time encoder.

Hexadecimal colors are based on the RGB color model, used since the early days of photography.

The theory behind the model is that you can create virtually any color the eye can see by assigning different combinations of red, green, and blue color values. The RGB color model is used by televisions, digital cameras, and video projectors, as well as virtually every computer and phone display out there.

The web and most digital applications use a color scale of 0 to 255. You (or a programmer) tell the screen how much red, blue, and green to display. This combination creates the color that the viewer sees.

You have a lot of freedom to choose the color you want. The total number of possible combinations is 16,777,216, more than the human eye can distinguish.

What is the difference between RGB and Hex codes?

Programmers prefer hexadecimal color codes because they are predictable. It is always six digits, regardless of color. RGB values ​​can be as few as three digits and up to nine digits.

You don't need to use hexadecimal codes in web design. When coding an HTML page, you can also use RGB values ​​or even color names.

For example, this is what HTML would look like if you were coding a navy blue background for a web page.

  • Aquamarine hexadecimal color code:<div style="background-color:#7FFFD4″></div>
  • Aqua RGB Color Code:<div style="background-color:rgb(127, 255, 212)"></div>
  • Aquamarine color designation code:<div style="background-color:aquamarine"></div>

Although you can provide the RGB name or code, that doesn't mean you have to. To reduce the chance of making a mistake in your design, use a hexadecimal color picker or converter to generate the desired hexadecimal code. That way, there's less chance that a current or future developer will try to do the conversion and turn your beautiful web page into something ugly.

Color streaks are more likely to appear on older devices that cannot display millions of colors. In modern CSSYou can program gradientsto eliminate the problem of colored streaks. On modern displays, color banding is more common in photos with natural gradations, such as skies and rainbows, where the millions of colors visible to the naked eye are compressed to save storage space.
