I didn't count the local channel 4 news color telecast every night or their other local color broadcasts plus the two daytime NBC quiz shows.
That would up the number of color shows available each week. Just for yuks here's the color listing for Los Angeles for the week of April 4th 1959. 46 years ago this month:

"Growing World" Sat. (channel 4 local)
"Vacation Time" Sat. (channel 4 local)
"Bugs Bunny" Sat. (channel 5 local)
"Northwest Passage" Sat. (channel 4 NBC)
"Perry Como" Sat. (channel 4 NBC)
"Steve Allen" Sun. (channel 4 NBC)
"Dinah Shore" Sun. (channel 4 NBC)
"Local News" daily (channel 4 local)
"Curt Massey" local daily music show (channel 4 local)
"Arthur Murray" Mon. (channel 4 NBC)
"Jimmie Rodgers" Tues. (channel 4 NBC)
"Price is Right" Wed. (channel 4 NBC)
"Milton Berle" Wed. (channel 4 NBC)
"Bell Telephone Hour Thurs. (channel 4 NBC)
"Masquerade Party" Thur. (channel 4 NBC)
"Ellery Queen" Fri. (channel 4 NBC)
"Haggis Baggis" daytime (channel 4 NBC)
"Truth or Consequences" daytime (channel 4 NBC)
This was an especially good week for color set owners. At least one network color show each night.

Another example is the TV Guide L.A. Edition week of Jan.14, 1956 over 49 years ago. Total color telecasts for the entire week: 3
Ford Star Jubilee Special Sat. (channel 2 CBS) live
NBC Opera Theater Sun. (channel 4 NBC) live
Matinee Theater Daily (channel 4 NBC) live?
