Both from RAL Classic's palette. Turquoise blue (LRV 23) reflects noticeably more light than Water blue (LRV 16), a difference of 7 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.

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.
