I think many people call a high quality spider , one with reduced pattern, minimal to NO 'dots' and medium to high whites, also preferably lighter in color. Some spiders hatch out lighter or darker than others, if your pushing for bees in the future, get yourself a nice clean light colored spider.
One personal thing is do you like the way she looks for yourself? Some people actually perfer their spiders or bee's to be more 'dotty' cause of the contrast, but generally in bees , when they are too dotty it makes them look more 'dirty' on their backs where they usually start to brown out.
