Hi.
That's an excellent result and well worth the effort.
I tried to find something similar a while back but had no luck. A search for coloured transparent polyolefin didn't throw up much. A search for polyolefin translucent colours was more successful. This company
http://www.insultab.com/products/dec...ink-specs.html looks to stock a wide range of various polyolefin finishes.
