RGB para Hex

What is RGB, anyway? rgb stands for Red, Green, and Blue. These are the primary colors of light and they form the rgb color model.

The Rgb color model is an additive color system (as opposed to subtractive) in which red, green and blue lights are added together at various proportions to reproduce a vast array of other colors.

Rgb values usually come in a 0-255 scale and often look like this: rgb(0, 74, 255).

On the other hand, a hex color code is a way of specifying colors using hexadecimal values.

The code itself is a hex triplet, which means it represents three separate values that indicate the levels of the component colors. A hexadecimal color value is made up of a string of six or three characters preceded by a hash (pound sign). The string often consists of 0-9 numbers and A-F letters.

Great examples are #FFFFFF which is the hex code for white and #000000 for black.

While rgb color model is mainly used to represent or display graphics in electronic systems such as televisions, printers, and computers, hexadecimal is more often used to specify colors in HTML and CSS code-powered elements such as web pages.

This is just about the only marked difference between the two color systems. Other than that, rgb and hex are just two different ways of expressing the same thing: a red, green and blue color values.

• Hex color values are in the form of a single string. If you are working on a team with software engineers, try using hex color numbers as they’ll be able to easily copy and paste the code off of a chat or email document.
• If you need to set the opacity of a colored object, RGBA provides this functionality. You can declare red, green, and blue values, and an additional value for transparency.
• Hex color codes are more compact, and therefore are better for minimized code. They can become even more compact by using only three digits for some colors (e.g #FFF), rather than the full six digits (e.g #FFFFFF).
• Hex improve the load time of a web page slightly. Computers handle binary digits, and one hexadecimal digit can easily be converted into four binary digits, while decimal digits take longer to convert.

These are obviously some of the reasons to convert rgb color values to hex codes.
