I like the orange ones personally but......
And light blue was all over Houston, although I've escaped there!
NFPA 291 Hydrant Color Coding:
Light Blue: Over 1500 GPM – Excellent flow
Green: 1000–1499 GPM – Good flow
Orange: 500–999 GPM – Marginal flow
Red: Less than 500 GPM – Poor flow, not suitable for firefighting
