Slightly exaggerate an account and blush (6)

I believe the answer is:

colour

I'm a little stuck... Click here to teach me more about this clue!

'blush' is the definition.
(I know that blush is a more specific form of the action colour)

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for colour that I've seen before include "Hue, tint" , "Quality that results from light reflection" , "Red or green, say" , "black?" , "Hue, shade" .)

I've seen this clue in The Globe and Mail and The Irish News.
