-Increase or decrease the intensity of the color of the element it is applied to.
+In CSS, the `saturate()` function increases or decreases the [color](https://www.codecademy.com/resources/docs/css/colors) intensity of an element.
 
 ## Syntax
 
-```css
+```pseudo
 filter: saturate(<value>);
 ```
 
-where a required `<value>` can be one of the following:
+The required `<value>` can either be a positive decimal number or a positive percentage number, such as (but not limited to):
 
-- Number value: `0`, `1.5`
-- Percentage value: `100%`, `50%`
+- Decimal value: `0`, `0.5`, `1.0`, `1.5`, ...
+- Percentage value: `0%`, `50%`, `100%`, `150%`, ...
 
-**Note:** Value defaults to `1` or `100%` leaving element unchanged. Higher values will increase saturation. A value of `0` and `0%` will remove all color leaving the element completely unsaturated. Negative values are not allowed.
+> Note: The value defaults to `1` or `100%`, leaving the target element unchanged. Higher values will increase the saturation. A value of `0` or `0%` will remove all the colors, leaving the element completely unsaturated. Negative values are not allowed.
 
-## Example 1
+## Example
 
-Set the saturation of a color to `25%`:
+The following example sets the saturation of a color to `50%` and `1.5` (or `150%`):
 
 ```css
-.banner-image {
-  filter: saturate(25%);
+.logo-image-2 {
+  filter: saturate(50%);
+}
+
+.logo-image-3 {
+  filter: saturate(1.5);
 }
 ```

+Here is the output for the above example:

+
+Here, the first image shows the original saturation at `saturate(100%)`, the second image is less saturated at `saturate(50%)`, and the last image is more saturated with `saturate(1.5)`.
