I say lye-lack. I don't think it is namey enough in sound ... the "ack" sound makes it seem contrived. Seems flimsy like Tulip or
Daffodil. The color is too pale and delicate to be inspiring (I feel the same way about
Lavender,
Cyan, and
Saffron).
Lilac A. Rug
... just kidding
It needs a quirky or even kooky middle name. Traditional-pretty names don't sit right near it IMO.
