WGN-TV "Color Presentation" IDs

Background
WGN-TV airing programs in Color from 1967 to 1973.

Opening ID (1967–1973)
Visuals: On a black background, we see the 1960's WGN-TV number "9" colored in white. The number 9 starts to disform it when the 8 colored teardrops come out: 4 of them are in top of the semicircle, and 4 of them are in bottom of the semicircle. All of them are zooming out until the number 9 disforms, the half parts are moving up and down as the word "COLOR" in the Microgramma font pops up. The words "WGN TELEVISION" in the same font appears below it.

Technique: Color animation.

Audio: A 8-note classic theme when the teardrops come out, and then the rest of the classic theme as the "COLOR" pops up.

Closing ID (1967–1973)
Visuals: On a black background, we see the colored circles overlap together to reveal the black number 9 from the opening ID, but connected. Then it fades to the colored teardrops to make the normal one from the opening ID, but in different colors. The words "WGN TELEVISION" appears one-by-one as it moves up and down. The words "COLOR PRESENTATION" appears below.

Technique: Color animation.

Audio: Two different classic themes, or the theme from the opening ID.
