Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. The distinction reads clearly at room scale, making the choice between them concrete.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. The distinction reads clearly at room scale, making the choice between them concrete.

5 simulated room previews — drag the slider on each to see RAL 850-3 on one side and Functional Gray on the other.
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.
