Hard to see if I have upvoted a post

When I upvote a post, the color of the upvote arrow becomes a dark blue color. This color is not dramatically different than the default dark gray color on the upvote/downvote buttons. When I scroll through a community, it's hard to see which posts I have upvoted because the upvote and downvote colors are so similar. Can Digg update the design to make it more clear for users to see which posts they have upvoted?
