First, here is the total set by color of the base cards and the complete set listed by category:
Yellow and red frames dominate the set. And by a wide margin obviously. Yellow is far ahead of second place red. And the 95 red cards are more than double the number of any other color. Between the two they represent about 48% of all the single player base cards.
And here is the American League broken down by color of the base one player cards:
Interestingly, among the AL cards red is the dominant color and 91 of the 95 red cards in the whole set are of AL players. Four clubs clearly have red as their dominant color. The Tigers, in fact, have only five of their 31 cards in a color other than red. Yet, of the remaining four clubs, two don't have a single red card and the A's have only one. Of those other four only the Red Sox are not primarily represented by yellow framed cards. The Bosox have no color that they can call their signature color in the '59 set.
AL observations.... Kansas City has the AL's only black frame and are the only team here that is represented by eight different colors. They lack a dark green card (ironically I think given their later history). They also are noteable in that there are six colors which appear on one or two of their players' cards.... the Yankees have the fewest total base cards (28). I'd have lost a bet on that one..... the White Sox have cards in only three different colors while the Orioles, Tigers and Yankees are seen with four....
This next chart tracks the colors of the team card (the frame is listed first, inner circle color next). It also shows the number of players each team has in the various subsets, All Star Selection, the Rookie Stars, Baseball Thrills (called High Lites in the chart's header), The center column gives the colors of the 'special multi-player cards (if they feature players from one specific team, called one team specials here). The same naming convention as the team card applies.
