Ο guide this will help you to understand more the web colors, which are written in RGB or hexadecimal form.
If you have ever worked on designing a web page in HTML, or have tried to change the background color of your social profile, you have probably seen the hexadecimal color codes. This is a series of 6 characters - like "0066FF" - which as you know represent the colors. But rarely have you made an effort to understand them.
Here's a simple guide to help you recognize web colors faster than the RGB codes themselves.
In a standard code #RRGGBB, for 2 the first digits indicate the red, the 2 second digits are for the green and while the 2 last digits represent the blue.
Each number indicates the strength of that particular color - say FF0000 it is only red (not green, not blue), the 00FF00 is green only (not red, not blue). If all the colors are in F then we have it Ffffff (white). For black, just give zero value to all 000000 colors.
If you want to darken a color, you need to move the color to the black 000000. This means that 880000 will be darker than BB0000 that is darker than FF0000.
Likewise, if you want to "lighten" a color, you can go for white FFFFFF. Thus, the FF8888 is more open than the FF4444 which is more open than the FF0000.
Color combinations are dictated by the "strongest" color. So the BB8844 is a reddish hue, the 33CC00 will be a little green, and the 777777 will be gray (since there is no stronger color).
For those interested, the RGB code for its blue color Facebook is # 3B5998.
If you are not an expert with hexadecimal arithmetic, you can use the standard Windows calculator in scientific mode to perform these calculations. Hexadecimal numbers use 16 unique characters (0-F), unlike the English alphabet AF used in decimal system 10 numbers (0-9), to make up for the extra 6 characters.
