The space needle is over 500 feet tall. I'm assuming that the building they're talking about is the Chihuly exhibit which is about 40 feet tall according to their website [0]. There are plenty of vantage points around Seattle where you can see the space needle but not see what's next to it on the ground.
In which case the interviewee should say, "I can't see the short building next door, so I'm not sure what color it is." But the post said the interviewee just lied and said "white".
