Factorio Forums

It is just like random_tint for item, but it dynamically choose the middle color depand on its spoilage level, and then applied the random_tint .

For example, I can give item-nutrients a brown tint, as it spoils, it will be more into the darker color before it become a real spoilage, and it might also solved the problem with Non-Alt mode cannot see items spoilage level problem.

I think the next level (different picture depand on spoilage) can be nice too.

Not sure I'm getting this right ... Is is for modding purposes ?

Half of it is, Half of it isn't, Factorio in the most part really can be play with alt-mode off, but spoilage is just a weird exception.
