Color-coded lunch boxes for allergens don't really exist — but these come close.

There isn’t a lunch box with official color-coded allergen compartments, but a few brands get you 90% of the way there with separate sealed sections.

Yumbox is the go-to for allergen parents. The compartments are physically separate and deep enough that foods don’t spill into each other, even if the box gets thrown around. The “Original” has 4 compartments; the “Snack” has 3. No color-coding built in, but the sections do the job.

PlanetBox is the better long-term buy. Metal, dishwasher-safe, and it comes with silicone cups you can buy in different colors — red for gluten, blue for dairy, whatever system you want. The cups snap in firmly, so cross-contact is unlikely. It’s pricier but survives years of abuse.

Bentology is the one brand that’s actually organized around color-coding. They sell bento bags and small colored containers that fit inside them. It’s not a single lunch box, it’s a system of separate colorful containers — which is honestly the safest setup for a severe allergy anyway.

One honest warning: compartments in a bento box cut down on cross-contact, but they don’t offer protection from crumbs jumping around in a shared bag. If your kid has a serious allergy (not just an intolerance), skip the single-box approach and use fully sealed individual containers like the Bentology cups or LunchBots with leakproof lids.

The right answer is sealed compartments, not paint colors.
