A few things. First, most color sets made before 1960, the earlier the more this is true, had paper capacitors in them while post1960 sets used more film based caps. Monochrome sets before film caps were about as bad as color sets were. Earlier models tended to be overcomplicated and the more parts with fixed failure probability the higher the probability of the device failing as a whole.
Many color sets into the mid 60's were RCA based and RCA used circuit boards. Boards are not the best thing to put tubes on and tend to fail from heat.

When Zenith entered the game it was not uncommon for their sets to last a solid decade maybe with some work. GE potracolors somehow use fewer parts than some monochrome sets of their day and tend to last longer than those sets as well...Ultimately in a really good design (there were many mediocre/bad ones) the more parts in the set the sooner it dies...Color had more parts on average.
