I think you are mostly right, however, I think you could have handled it better (i.e. scolding him in front of the kids, you could have asked him to another room or something)
The husband is not a dictator. He is the final word on many things, but there are, or should be, "wife things" where she is the boss.
Examples are: talking to the female children about puberty, menarche, etc
The *inside* of the home: decor, organization. The "infrastructure" (plumbing, wiring, structure) are man stuff. The lawn, gutters, painting the outside, setting up a swingset etc are mostly man stuff.
Decorating the inside, changing the color of the house, the flowers etc, should be woman stuff and she should get the final say.
Since it's about organizing the inside, I consider this woman territory. Men have junk sometimes. Women banish them and their junk to a/the garage or a basement, or somewhere where she agrees she has no say. Some men label it the "man cave". I collect ships in bottles. My wife doesn't understand why I need more than one, nor do I, but I have them. I have a designated man cave for my ships, my computer junk, and if I'm working on a model I can leave the model and glue and xacto knives laying out. She says nothing about the condition of that area. I have beer fermentation going on in that space sometimes.
You are "right" but you two need to carve out your domains of responsibility and establish them to avoid future arguments.
You really need to support his authority and not scold him in front of the kids, when kids are teenagers they'll challenge their parents at some point, and Dad is usually the one to bring the hammer down on that. If they see you treat him like that, they won't be scared of him.
