# --description--

In the additive RGB color model, <dfn>primary colors</dfn> are colors that, when combined, create pure white. But for this to happen, each color needs to be at its highest intensity.

Before you combine colors, set your green marker back to pure green. For the `rgb` function in the `.two` CSS rule, set green back to the max value of `255`.

# --hints--

Your `.two` CSS rule should have a `background-color` property set to `rgb(0, 255, 0)`.

```js
assert(new __helpers.CSSHelp(document).getStyle('.two')?.backgroundColor === 'rgb(0, 255, 0)');
```
