Is it possible for us to create new effects like perishable and wetness?

[HomShaBom]

When an item is perishable it has a green, yellow, or red background depending on how spoiled it has become. When an item is wet it has a blue border around the item and the border becomes thicker with wetness.

In the perishable component i couldn't find anything that was coloring the background. I also cannot find what is causing the "Stale ", "Spoiled ", or "Wet " prefixes to display on the item name. I know that's handled through tags. If you put add a "stale" tag to an item its name gets prefixed with "Stale ", but I cannot find what is adding that prefix to an item name.

Are we able to create our own components that have these kind of effects? Are these being handled in lua somewhere that I can look at and model mine after?
