You copied that wrong. 3272 through 3278 were all monochrome (green from IBM, and at least one competitor had an easy to work with cyan); the first IBM color tube was the 3279, but it only had 7 colors and black. The 3279 also had triple-plane graphics, which allowed for some nifty user created characters.
The 3290 could be configured as 4 24*80 screens, but also other sizes and combinations (e.g., one popular combination was 2 24*80 on top, 27*132 on bottom; once TSO supported it, 52*160 was also used).
