**Hex Code for Color**

All graphic design software and companies use hex code to get exact colors for their use. Hex code can pinpoint any color within the visible spectrum and is a great reference guide for people struggling to find a color. Hex code is 6 characters long, each set of two representing a channel (Red, Green, Blue) and how "bright" that color is shinning.

**White**: For white, all channels are at its highest point or #FFFFFF. **Red**, **Green**, and **Blue** are all at a maximum value of 255 when white color is selected. If F is equal to 15 then 255 will be FF or 15*15. So if 255 is FF then the RGB values would be R:255, G:255, B:255

```
R:FF, G:FF, B:FF
```

```
#FFFFFF
```

On the other hand, Black is the absence of light or color. It's hex code would be:

```
#000000
```

Similarly:

- Pure Red -
#FF0000

- Pure Green -
#00FF00

- Pure Blue -
#0000FF
