when they say light gold, i do actually think in person it is a very goldy gold so do be cautious if you think light gold will really be light gold.
there are a lot of different blues actually available like leooh said,and although there tend to be seasonal variations there are usually a few different blue shades released within a year. a blue would be unlikely to show colour transfer. right now there is a dark turqoise blue with embellished strap though personally i am not a fan of the embellished strap. there is a picture of this on this thread

other blues are released every so often so if you dont find the perfect blue yet, keep an eye out. there was yves klein blue fairly recently i remember. blue tends to come out with silver hardware from what i remember. from what you say of your waldrobe i agree that maybe blue is worth considering.
