Steel Symphony 1 vs Alley Cat
Where Steel Symphony 1 belongs to Dulux's range, Alley Cat is a PPG color. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. Steel Symphony 1 (LRV 17) reflects noticeably more light than Alley Cat (LRV 13), a difference of 4 points that becomes especially apparent in rooms with limited natural light.
