Because the shades don’t blend, the display ends up being distinct bands of color (color banding).Ĭolor banding is more likely to happen on older devices that aren’t able to show millions of colors. When web designers try to create gradients using hex colors, the results aren’t always as expected. But because every pixel must display a unique color, hex colors don’t allow you to blend between shades of different colors very well. With 16,777,216 potential colors, hex color codes allow you plenty of options for contrasting colors. Here are a couple of things to know to make your project go well. If you’re used to working with colors in Adobe Illustrator or for print, working with hex colors on the web is a bit of an adjustment.
That way, there’s less chance of a current or future coder trying to do the conversion themselves and turning your gorgeous web page into something unsightly.
HEX FOR 255 255 255 CODE
To reduce the chance of a mistake in your project, use a color hex wheel picker or converter to generate the hex code you want. Here’s how the HTML would look if you were coding, say, an aquamarine background for a web page.Įven though you can specify the name or the RGB code doesn’t mean you should. If you are coding a page in HTML, you can also use the RGB values or even color names. You aren’t required to use hex codes in web design. RGB values can be as few as three digits and as many as nine. They are always six digits, no matter what the color. Hex color codes are preferred by programmers because they are predictable. What Is the Difference Between Using RGB and Hex Codes? The total possible number of combinations is 16,777,216 which is more than the human eye can actually distinguish. You have a lot of freedom to pick the color you want. That combination creates the color that a viewer sees. You (or a programmer) tells the screen how much red, blue, and green to show. On the web and most digital applications, a 0 to 255 color value scale is used. The RGB color model is used by televisions, digital cameras, and video projectors in addition to practically every computer and phone screen in existence. 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. Hex colors are based on the RGB color model that has been in use since the early days of photography. Romantic background for a wedding or other personal page Subtle background for an eCommerce or corporate page This knowledge might come in handy if you were designing with a coder on the fly. You always can use a converter to convert the RGB numeric values into hex code for you.īut it may be helpful to memorize a few of the more common hexadecimal colors. So, of course, most will be somewhere between. The hex color values can combine to show more than 16 million different colors. 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.
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.
