Yes — "blue" is one of the first color sight words. Its "ue" ending makes a long "oo" sound that's less common than other spelling patterns, so it's introduced early through sight recognition.
The sky is bright blue today.
"Blue" follows a less-common vowel pattern ("ue" making a long "oo" sound) compared to more familiar patterns like the double "o" in "moon". Since color words appear on nearly every page of early picture books, "blue" is taught by sight well before this particular spelling pattern would normally be introduced through phonics instruction.
Compare "blue" with "glue" and "true" — showing this small family of "ue" words helps the pattern feel less like a one-off exception.
