VT220 was monochrome, too. You needed to go to the VT241 before you got
color in the DEC terminal range (and even it didn't support color text
via the SGR sequence (CSI m), according to the manual -- even the VT510
manual doesn't document colored text via SGR.)
MS-DOS ANSI.SYS definitely only had one attribute at any time; new lines
was filled in with the current attribute.
