4th Logo (1991-1992)
Nicknames: "Dutch Rhombus I"

Logo: In a building in which the sky can be seen through the windows and doors, there is a checkered floor. Several tiles of the floor float and turn into a blue diamond, then a yellow number 1, and then back to a tile, and the process keeps repeating. The tiles are in an infinite loop, and the logo forms briefly every time the yellow 1 is in front of the blue diamond. The then-new Nederland 1 logo of the time is at the bottom-right corner.

FX/SFX: The CGI animation looping, kinda reminiscent of GIFs from today. Designed by Lambie-Nairn.

Music/Sounds: A jazz tune with the same four notes repeating in the background.

Availability: Extinct.

Editor's Note: None.

5th Logo (1992-1996)
Nicknames: "Pattern Rhombus", "Dutch Rhombus II", "Fog Rhombus"

Logo: We see a wide rhombus displaying various patterns/images while zooming out. It's seen with the top facing the camera. Once the rhombus stops zooming out a light appears illuminating it, and we see coins in the left side of the screen when that happens. Then a blue rhombus (not very wide like the previous one) fades in and the yellow "1" appears on the center of it.

Variants: Depending on the program genre, the background and patterns that show in the rhombus change:
 * Entertainment: Dark zebra pattern background, the rhombus shows other zebra patterns with different colors.
 * News: Black background, the rhombus shows a weird pattern (it is maybe a stone pattern or the world map at night). There's also fog in this variant, which later intensifies at the second half of the logo. To end, the logo fades out in a white color.
 * Current Affairs/Information: Static-like background, the rhombus shows various texts of "Info" in various fonts and colors. Fog is also shown at the 2nd half part of the logo, but it clears out near the end.
 * There's also a ident which shows a black background and fog, with the rhombus displaying various colorful patterns. The fog also intensifies at the 2nd half of it.

FX/SFX: Pretty nice animation.

Music/Sounds: Depends on the variant shown.

Availability: Extinct.

Editor's Note: It depends on the variant shown, but not all of them are very scary or notable.
