How HTML Color Codes Work

Ever wonder how HTML color codes are put together? For the beginner, it can look like lots of numbers and letters that make no sense. In reality, HTML color codes are written that way for a specific reason that we'll look at in this article.
Introduction to the Hexadecimal System In mathematics, the hexadecimal or simply hex is a numeral system with a base of 16 usually written using the symbols 0-9 and A-F. The numbers 0-9 have the same value as in the decimal system but starting with the letter A, the value keeps going up one up to the value of 16. A is worth 10, B is worth 11 and so forth until you get to F which is worth 16. How the HTML Color Codes are put together HTML Color codes are composed of six hex numbers that represent a possible 16.7 million color combinations. The hex color codes are built on the RGB color model. R stands for red, G for green, and B for blue. With your typical html code that looks like this: #FFFFFF it breaks down as follows. The first two hex digits #FFFFFF represent 'red'. The second set of two hex digits #FFFFFF represent the color green. The third and final set of two hex digits #FFFFFF represent the color blue. A brief overview of the RGB model The RGB color model, like the HTML color model can represent a total of 16.7 million colors. By varying the amoung of red, green, and blue, one can come up with any of 16.7 million colors. Each RGB value is represented by a number from 0 to 255. So a set of RGB values for the color white for instance, would look like this: 255, 255, 255. Putting HTML and RGB Together We've already established the hex numeral system with it's number range between 0 to 16. Now, when you combine two hex numbers, you can represent any number between 0 and 255. As you can see, RGB and HTML color codes represent the same color model. Websafe Color Palette Years ago, monitors could only display 256 colors. These monitors were still popular when HTML was first put together. As such, it was necessary to put together a list of colors that web designers could be sure any given monitor could properly display. Web safe colors are the result. The websafe color palette is made up of 216 colors.

HTML Color Picker

Use the slider on the right to change the hue. Click anywhere in the large square to pick a color. Once you're happy with the color, copy the hexadecimal value from the bottom field, the series of 6 digits, e.g. #C51546.

/ Uporabite drsnik - hue za spremembo odtenka. Kliknite kjerkoli v velikem kvadratu in izberite barvo. Ko ste zadovoljni z barvo, skopirajte heksadecimalna vrednost v spodnjem polju, serija 6 ?tevilk oz. ?k, npr. #C51546.

Web colors are colors used in designing web pages, and the methods for describing and specifying those colors.Authors of web pages have a variety of options available for specifying colors for elements of web documents. Colors may be specified as an RGB triplet in hexadecimal format (a hex triplet); they may also be specified according to their common English names in some cases. Often a color tool or other graphics software is used to generate color values. The first versions of Mosaic and Netscape Navigator used the X11 color names as the basis for their color lists, as both started as X Window System applications. Web colors have an unambiguous colorimetric definition, sRGB, which relates the chromaticities of a particular phosphor set, a given transfer curve, adaptive whitepoint, and viewing conditions. These have been chosen to be similar to many real-world monitors and viewing conditions, so that even without color management rendering is fairly close to the specified values. However, user agents vary in the fidelity with which they represent the specified colors. More advanced user agents use color management to provide better color fidelity; this is particularly important for Web-to-print applications
