They do

British write it Colourado

On a related note, the first person to print Shakespeare's works was colorblind. That one play was supposed to be called "Much Colorado About Nothing".

Now without further ado...

Fun fact: the American Sign Language for Colorado is just the word “color” followed by the word “do”

I wonder if blind people read ado as just ado? What?

Do Canadians spell it Colourado?

I will always upvote a post which mentions the place I live

If it was named "Coloredo", they would only see "o"

In this line of thoughts I wonder if Traditional English people spell it as Colourado.

Colorado in Spanish means "red", so colorblind people can't tell apart Colorado from Greenland. That's a fact.

I get high like Colorado

We had it all but what do I know?

I wonder if people read "read" as "read" or if they read "read" as "read".
