1st Logo (September 19, 2007-March 31, 2022)

Variant: On Significant Mother, the background is completely white for the entire duration of the logo.

Technique: CGI.

Music/Sounds: None.

Music/Sounds Variants:
 * On Pretty Little Liars, the start of the end theme plays over the logo.
 * On the short-lived show Significant Mother, a shining sound is heard.

2nd Logo (August 7, 2020-)
Logo: On a light blue-white gradient background, we see various layers of the four-leaf clover logo in zooming out and rotating. Once the clover is almost finished forming, the company name from before rotates in letter-by-letter below the clover, with a shadow forming below them.

Variant: A short version that starts when the text rotates in exists. The clover is already formed here.

Technique: CGI.

Music/Sounds: None or the closing theme of the show.
