Passage: In 2000, ABC launched a web-based promotional campaign focused around its circle logo, also called 'the dot', in which comic book character Little Dot prompted visitors to 'download the dot', a program which would cause the ABC logo to fly around the screen and settle in the bottom-right corner. The network hired the Troika Design Group to design and produce its 200102 identity, which continued using the black-and-yellow coloring of the logo and featured dots and stripes in various promotional and identification spots. Question: What colors was the 2001 ABC logo?
A:
black-and-yellow
