Depends on where you live and also what your wear. Blush worn with soft neutral colors in heavier fabrics would look great, even in the coldest climate. Pair the blush with tans, corals, soft grey, off white, etc. and you will look like a fashion icon. Would even look great with black or navy or brown. Wear the blush with jeans and a plaid shirt.... well, the blush will look out of place. 
Bottom line, make it look like you planned the outfit not like you just reached for the handbag you've been using all summer.
