Back in the day ................. way back ..............like before "pure" ice and debates about draining VS not draining ..........
we used Gott coolers. We had white, and we had Dark red, and we had Dark blue.
We'd pack 5 day trips, pack the food two days before launch, and with notable exceptions always had ice at the end of the trip. Or, at least cold beer.
It didn't much matter the color of the cooler. What mattered was packing the thing properly, sealing it tight, and not ever, ever opening it until you were ready to use what was inside. One cooler a day for the food;
1st day dinner, 2nd day breakfast, and 2nd day lunch went in the first cooler. 2nd day dinner, 3rd day breakfast and 3rd day lunch in the second cooler. And so on.
When we hit camp on day one, out came dinner to defrost. The lunch cooler was repacked with 2nd day lunch. 2nd day breakfast stayed in the cooler with whatever ice was left. In the morning we'd empty out breakfast and if we had ice left over it went into (my) beer cooler.
The uninformed were welcome to keep their damn hands off of the food coolers. Uninformed who even looked at a food cooler were given strict instructions to get the fuck away. We'd pull knives to enforce the point.
It worked.
As I said, color was (is) irrelevant.
What mattered was the packing.
Tan VS white? It was me, I'd go for the cheaper one.
Same price?
Just pick one.
Just goddamn pick one.
