Items without color definitions cause debug message

[BevapDin]

Describe the bug

The item "plastic sheet" (id "plastic_sheet_small") has no color in its definition (file "data/json/items/resources/plastic.json").

When an item of that type is on the map and it gets highlighted, a debug message appears, complaining about the invalid color. May only appear in the curses version.

Steps to reproduce

Spawn a "plastic sheet".
Drop it on the map, on an empty normal floor tile (one that shows up as "."). The item should be visible on the floor as a ",". it should be the only item there.
Highlight the tile (use the "Look Around" feature).
Get the message.

Expected behavior

No debug message.

Even better would be a check during the loading of the item definitions that all items have a valid color.
