I'm talking about items like many containers (cupboards, barrels, crates, coffers, stone casket, large chest, mannequin, wooden chest, wooden box), some production&processing items (bee skep, herbalist table, tubs), some workstations (anvil, churn, meat grinder) and most furnaces (oven, smelter, crucible, finery forge, tar kiln), and walls (dry stone walls, brick walls, palisades). Probably there are some items I forgot to mention.
There are two reasons to add material-based texture to items. The first and most obvious is aesthetic: it looks nice to have things of different colours, based on what you used to build them.
The second reason, and most important, is color coding.
Gates of different color could be associated to different keys, making it much easier to know which key you need for each gate.
Barrels of different color could be designed for different seeds or liquids. Cupboards and chests with a specific design could tell villager that those are only for a specific kind of items, like let's say Cherry red for first aid supplies.
This could also work for items with quality, even if less likely, like tubs.
We already have such a feature on many items of many different materials, both quality workstations and random stuff like wilderness beacons. Could we please get it on more stuff?
