I reckon they chose blue because in real life whan fighting flames they wouldnt have been able to see them in a darkened room full of smoke and flames. Its one reason why we changed from black helmets to yellow ones, I remember the yellow paint arriving, it was so hilarious to see all these old firemen painting their helmets yellow, they were so grumpy, and looked like a row of daffodils on parade LOL, takes me back to 1976!
More black on helmet and belt Id suggest if you want to get closer to real life. Not that im critical as I cant do it! Red I ask you!
