I've tried blunt as a contour before, but unfotunately it was a tad too dark and reddish on my NC35 skin - but it's a great contour shade nevertheless - use it to contour in the hollows of the cheeks, and highlight with honour or trace gold blush - the result is fantastic!
definitely a good contour shade -- but use a light hand and build gradually. the color is pretty deep and as someone else mentioned, can end up looking reddish-toned if you apply too much (like a lot of bronzers)
