Great quiz! Correct me if I’m wrong but I believe Washington DC should work for the blue categories, as “DC” is not part of the name of the city, but just indicating the federal district.

Actually, on all quizzes we use "Washington, D.C." and even Wikipedia does as well, stating "also known as Washington", indicating it treats them as different things. Yes it refers to the district, but it's also a part of the name.

Just like Kansas City indicates that it's Kansas, the city, instead of Kansas, the state. But it's still part of the name.

Except the name is not "Kansas, City" it's "Kansas City" and your comparison doesn't make sense

As someone who has gone to Kansas City all his life, I've had to patiently explain to so many people that while I had a fine time in KC, I generally did not get to Kansas at all.

Washington is definitely a one-word capital. The rest of the world can't help it if, to differentiate it from the state, Americans frequently add the "D.C." to the name.

Also, Astana is definitely also a one-word capital. I assume this absence is just a missed change from the Nur Sultan period.

Kansas City is referred to as Kansas City because that is literally what it is called. Washington, D.C., is like saying "Kansas City, Kansas" and then saying that's the real name

It's funny that Buenos Aires also contains the letter I, so i half-expected the last clue to be that too, just to make it more difficult. Are there any other capitals that contain all five vowels?

Just to let you know that Washington works for the Blue categories up to "which are only one word" where it does not work anymore although Washington is only one word.

No it's not. It's Washington, District of Columbia. Saying DC is part of it's name is like saying NY is part of the name of Albany, NY.

Astana should work for the second and third clues in the purple category; until they inevitably change the name again.

I believe Caracas should work for the Blue Categories. I assume the population refers to the metropolitan area rather than the actual city (as Khartoum would also not work otherwise), therefore I believe Caracas fits all categories.

Refer to the link in the caveat. The source shows Caracas at about 3 million people.

Under the purple category, Astana works for "Capitals whose country is landlocked," but doesn't work for "...which are only one word." or "...which are in Asia." Maybe the first line got reset from the big switch back from Nur Sultan, but not the following two lines?

I thought Europe and tried all of them I could think of. I did get it, though, because after doing Europe and then the few North and South America ones I could think of in the NH, I managed to just start guessing countries capitals that are in the NH and I got it.
