The Creative section of the Lumetri Color panel includes various looks that allow you to do quick color adjustments to your clips using already existing presets. Premiere Pro includes a number of creative looks that you can use. You can also create your own custom LUTs and save them to have them appear in this panel for easy use.
After applying a look, you can then adjust parameters such as vibrance and saturation.
The Lumetri Color panel provides a Looks Preset Thumbnail viewer. Click through the creative looks in the drop down list, or the arrows on the preview to different Looks, and click the image to apply a look to the clip.

Faded Film
Applies a faded film effect to your video. Drag the sliders to the right or left until you achieve the desired vintage look.
Sharpen
Adjusts edge definition to create a sharper-looking video. Drag the slider to the right to increase the edge definition, and drag to the left to decrease the edge definition. An increased edge definition makes the details in the video more pronounced. So, make sure that you don't sharpen the edges too much that it looks unnatural.
Vibrance
Adjusts the saturation so that clipping is minimized as colors approach full saturation. This setting changes the saturation of all lower-saturated colors with less effect on the higher-saturated colors. Vibrance also prevents skin tones from becoming oversaturated.
Saturation
Adjusts the saturation of all colors in the clip equally from 0 (monochrome) to 200 (double the saturation).
