I guess it depends on how often you will want to use the bag. Do you want to get your moneys worth?
Every time you carry a colourful bag, it will be, "oh, she's carrying that red bag again"... a beige bag doesn't scream like that. Scream in a good way of course, but to me it's not a bag you will want to use all that often. Just on special occasions. KWIM?
