beautification

My initial attempt (previous post) was not only slightly unsuccessful but it also was not very appealing looking. I was considering coloring the plastic, perhaps different colors for each section- and multiple placed on one tree. Thoughts? Spray paint? I'm not really sure how you color plastic. I have a red sharpee and considered doing designs but think that may look tacky and a solid color would be better.

I have also considered fastening a string to a stick and feeding it through the washer to have a sort of web coming down through the middle, perhaps placing a stick on that end as well. This could help with weighting down the water draining point and perhaps look neat?
