The color of a sprinkler head rated 175° to 225°F is which color?

Explanation:
Sprinkler head color identifies its temperature rating, so you can tell the activation temperature at a glance. The standard color mapping is: White for 135°F, Yellow for 155°F, Red for 165°F, Blue for 175°F, Green for 200°F, and Orange for 286°F. For a head rated around 175°F to 225°F, the lower end corresponds to Blue (175°F) and Green appears at 200°F, while 225°F isn’t a standard rating. So the color you’d expect for this range is Blue, not White.
