With Antenna TV purging all of its shows that are all in black-and-white, I thought I'd look into a schedule made up entirely of comedies that were all black-and-white:

5:00 am You Bet Your Life
6:00 am Maverick
7:00 am Dennis the Menace
8:00 am Leave It to Beaver
9:00 am Mister Ed
10:00 am Father Knows Best
11:00 am Donna Reed Show
12:00 noon The Bob Cummings Show
1:00 pm Bachelor Father
2:00 pm McHale's Navy
3:00 pm The Phil Silvers Show
4:00 pm The Real McCoys
5:00 pm Make Room for Daddy/The Danny Thomas Show
6:00 Our Miss Brooks
7:00 pm The George Burns and Gracie Allen Show
8:00 pm I Love Lucy
9:00 pm The Dick Van Dyke Show
10:00 pm The Jack Benny Program
11:00 pm The Many Loves of Dobie Gillis
12:00 midnight The Patty Duke Show
1:00 am (M-Su, four episodes) Amos ‘n’ Andy, The Addams Family, The Munsters, Car 54, Where Are You?, The Abbott and Costello Show, Lucy-Desi Comedy Hour, Honeymooners
3:00 I Married Joan
4:00 My Little Margie

Mister Peepers may not look good enough to play any time except very late at night.

There are short-lived shows, such as Ensign O'Toole and Mrs. G Goes to College, which turned up only briefly in syndication but looked pretty good. They could be deep filler.
