Signal yellow vs Broom yellow
Both from RAL Classic's palette. Signal yellow (LRV 49) reflects noticeably more light than Broom yellow (LRV 43), a difference of 6 points that becomes especially apparent in rooms with limited natural light. The ΔE 8.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
Signal yellow vs Broom yellow Color Comparison
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
