The Complete Beginner’s Guide to CSS

# RGB colors
We can use the `rgb()` functional notation to calculate the `color` from its RGB notation as an alternative to hex colors.

We use a list of three numeric values ranging from `0` to `255`. The first is our `red` value, the next is our `green` value, and the last is our `blue` value.


For example:

```css
color: rgb(255, 255, 255);  /* white */
color: rgb(0, 0, 0);        /* black */
color: rgb(255, 0, 0);      /* red */
color: rgb(34, 139, 34);    /* forest green*/
```

We can use the `rgba()` **functional notation** to adjust the opacity. With RGBA, we add a fourth value. The value is a number ranging from `0` (completely transparent) to `1` (completely opaque).

For example:

```css
p {
  color: rgba(0, 255, 255, .5);
}
```
