ELI5: How HEX code works and how you can tell what color it is by looking at the numbers/letters
Hex colors are broken up into six hexadecimal digits. There are three sections - Red, Green, and Blue (in that order). Each section is a number from 00 to FF. The higher the number/letter, the more of that color you have. Examples: Pure red is FF0000 Pure green is 00FF00 Pure blue is 0000FF Black is 000000 White is FFFFFF More on reddit.com

May 1, 2014 - A computer screen displays a color by combining red light, green light and blue light. 100% red, 100% green and 100% blue produces white. Zero red, zero green and zero blue produces black. In fact, equal levels of red, green and blue, whatever that level may be, will always produce a shade of gray. The six digits of a hex code are in fact three two-digit numbers, each representing the level of red, green and blue.

November 14, 2011 -

I am in Intro to Programming and our professor assumed everyone already knew this. I am also a graphic design major and don't know how I don't know this already, but I have googled a little bit and it all goes over my head.

EDIT*: Ahhhh! Now I see! Thanks guys! First thing I've posted to ELI5 and a great response!

Hex colors are broken up into six hexadecimal digits. There are three sections - Red, Green, and Blue (in that order). Each section is a number from 00 to FF. The higher the number/letter, the more of that color you have. Examples: Pure red is FF0000 Pure green is 00FF00 Pure blue is 0000FF Black is 000000 White is FFFFFF

Are you referring to the codes used to define colors, such as those used on website code? If so, those look something like this: color: #3399ff. Some background, in case you don't know. Each hexadecimal digit can have a value of 0-15. We only have numbers from 0-9, so we start using letters at 10. 10 = A, 11 = B, etc. Thus, each hex digit can be represented as either a letter or number, with a value of 0-F. Further, since the value is 0 - 15, each Hex digit can be used to easily represent four binary bits. 8-bit data values are composed of (wait for it...) 8 binary bits, and can have a value of 0-255. 8 binary bits can be represented by 2 hex digits (4 bits per digit). So any number spanning two hex digits can have a value of up to 255. Okay, now on to the code itself. First, know that this is an RGB code. The first part is the value for Red, the second for Blue, and the last for Green. Take this number and break it up into its three components: Red = 0x33, Blue = 0x99, Green = 0xFF. With a color, 0xFF (decimal 255) is used to represent max intensity and zero is basically "off". So a full bright red would be 0xFF0000. A pure blue would be 0x00FF00, and green would be 0x0000FF. White would then be 0xFFFFFF. Now, as for how you can just tell a color by looking at the number, that just comes with experience. For example, the example I used (0x3399FF) has a full-value for blue, less green and even less red. Turns out this is a light blue, which makes sense. Like most things, it will come with practice. I hope this helps! EDIT: just found this , it might help a bit.
