Choosing Colors on the Web
When creating designs for the Web, color is very important. It's also something that can be difficult to communicate to your designer. Thankfully, each color that can be displayed on your monitor has a special number assigned to it, and you can use these numbers to let us know what colors you need.
Hexadecimal Color Codes
The numbers used to represent colors are usually referenced in the hexadecimal (base 16) system. Because the common decimal system only contains 10 numbers, we use the letters A-F to add numbers past 10. For example, the number 29 in hexadecimal is 1D.
All colors on your monitor are comprised of a combination of red, green, and blue. By mixing these colors in different ways, using the hexadecimal system, we can create over 16 million colors! Each red, green, and blue value is assigned a number from 0 - FF (0 - 255 in decimal). The higher the number gets, the more intense that value will be. For example, if red is set to FF, blue to 0, and green to 0, you'll have a bright red color. This color combination is written as FF0000. The first two numbers represent red, the next two represent green, and the last two are for blue. So to get a teal color, we can mix green and blue like this: 006655. Wikipedia provides more information on this subject if you're interested.
Now that you have a basic understanding of how colors are written in hexadecimal, we can communicate more effectively in regard to the colors you need.
