Check out Accurate Lines. They have got some bright colors, including blue...maybe close to what you're looking for. Plus you can get combos with the handles. I ride with them...and love it!
Speaking of ropes/handles, is there something I should stay away from? I was about to order the one linked here but got cold feet because I couldn't touch it. I've been using some rope and handle my brother bought years and years ago and figured it would be better to get a new one and leave that one as a spare.
