Signal White vs Ceiling Bright White
Where Signal White belongs to RAL Classic's range, Ceiling Bright White is a Sherwin-Williams color. Signal White reads as white, while Ceiling Bright White reads as green-white — two distinct hue families, not close cousins. Signal White (LRV 85) reflects noticeably more light than Ceiling Bright White (LRV 83), a difference of 3 points that becomes especially apparent in rooms with limited natural light. At ΔE 1.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
