column replace
Hello. I'm trying to replace the 1st column of text with the word Blue. The string is text and numbers. Trying to learn awk and have been searching forums but can't come up with anything. Any help would be appreciated.

Code:
awk '{sub("[a-zA-Z0-9]*", "Blue", $1)}'1 file

Read about the "sub" function in awk.
