Raduga

1st Logo (1971-6 June 1972)
Logo: Two perpendicular white lines are positioned on the bottom right section, covering the second quadrant of a graph. To the top left is the stacked company name with "Raduga" in a cursive font and the rest in a normal font.

Variant: Sometimes, the copyright year may be added to where the lines are.

Technique: None.

Music/Sounds: None.

Availability: This is only known to appear on Физика в половине десятого and Математик и черт.

2nd Logo (15 December 1991)
Logo: A shirtless gongman hits a large, golden gong, breaking it into pieces. The camera zooms into the shattered hole of the gong where a nude blonde boy appears creepily staring at the screen. As the screen zooms out, it is revealed that the child is peeing. Then, a warm rainbow arcs around the boy, followed by the stacked company name in a white, serif font. Shortly after the text appears, the juvenile fades out, followed by the rainbow and the text.

Technique: A mix of live-action and cel animation.

Music/Sounds: A dramatic, synthesized sting for the majority of the logo. There is also the addition of the gong and water flowing. When the rainbow appears, an ascending, slow harp note plays.

Availability: Only seen on Имитатор. All of their other films released around this time uses an in-credit disclaimer.
