"The red shiny shoe lay on the grass beside ..."
The word placement here forces a literally "bloody image," as far as I am concerned. The placement of "red" before "shiny" makes it jarring to look at by the sheer awkwardness (a shiny shoe is awkwardly called red, but red shoe is fittingly shiny. consider "new shiny shoes" vs "shiny new shoes," for example), and so forces my eyes to consider the implications of "red" here. Considering the stress on red, I almost (not quite. again: a little awkward) see the shoe as coloured red by something that is not inherent to the shoe (like blood or spilled paint).
Further, the Red/Green opposition (They are literally opposite colours) makes the scene, for me, disturbing. By that I mean that it is a jarring or unnatural image to look at. This effect is doubled by the contrary state of the civil/natural "red shiny shoes," which read most likely as dancing shoes or heels, and the grass.
Honestly I think that you can change this into whatever you want by tacking on any ending, but I do think that the power of the statement is lost on a more complacent image. However, that's not to say that it has to be "horrific" (which my "bloody image" might have implied), because it can also be very sexual (blood being fertility).
"The red shiny shoe lay on the grass beside her pale body."
I had a sexual example, but I felt that it didn't contain itself within the passage at all, and required some external reference (either prior reference to sex or one to follow) or some exceptional wordiness. But I don't write so who knows haha.
