Soft, low-saturation colours — muted blues, greens and neutrals — are commonly chosen for bedrooms where a restful atmosphere is the priority.
Filtered for the same low-saturation, non-vivid profile used by the calming mood.
What makes a colour feel calming is mostly low chroma and moderate contrast: surfaces that do not compete for attention. Studies of colour and emotion, notably Valdez and Mehrabian's 1994 experiments, found that saturation and lightness predict how arousing a colour feels more strongly than hue does, so a soft muted green, blue or warm neutral is calmer than a vivid version of the same hue. A bedroom is also mostly seen in low evening light, where muted mid-tones hold their colour better than very pale ones.
What the filter selected: 49 of the catalogue’s colours pass this test. Their relative luminance — roughly the share of light a surface in that colour would reflect — runs from 0% to 100%, with a median of 35%. 0 lean warm and 24 lean cool.

Undertone caution: two colours in the same family can still read very differently once on a large surface, depending on their undertone — check against your existing flooring, furniture and fittings, not the swatch alone.
Lighting caveat: a colour can look noticeably warmer or cooler depending on natural and artificial light through the day — see the lighting guide for what specifically changes and why.
Finish caveat: matt, eggshell and gloss finishes reflect light differently, which can make the same colour read lighter, darker or more saturated depending on the finish chosen.
Always view a physical sample in the actual room, at different times of day, before committing to a large surface.
