Styrofoam is trademarked by the Dow Chemical Company. I am unsurprised by this; many things are semi-generic.
However, examining their footnotes you see: "**The color Blue is a Trademark of The Dow Chemical Company."
I'm unsure if they trademarked that particular colour, that colour when applied to styrofoam, the name of the colour, the name when capitalised, or what. The second would be logical.
