These are held together by depth rather than hue. Every one of them falls between L*69 and L*92 — light — across 3 hue families (green, cyan and neutral). The consistent lightness is what makes them combine without argument; the hues are free to differ.
They are not interchangeable. Chroma runs from 10 to 64 and lightness from L*69 to L*92, which is a wide enough saturation spread that the strongest of these will dominate the quietest if you use them at the same scale. Pick one to lead. They also split on undertone (neutral and cool), so pairing across that split is where this group most often goes wrong.
Assessed individually, most of this group comes out strong for trim and joinery, walls and large surfaces, secondary surfaces, furniture, rugs, curtains and bedding and accents and small objects. That is a property of the measurements rather than of the mood label — a colour does not become easier to use on a wall because it is described as muted.
At an average chroma of 25 these have enough colour to survive a change of light without collapsing, but they will shift. Warm bulbs will push the warm members further warm and drain the cool ones. Sampling matters here more than the swatch does.
Shared by at least half the colours in this group, taken from their own individual assessments.
The grouping itself is an editorial judgement — a mood is a convention, not a measured property of a wavelength. Everything said about the colours in it above is derived from their measured values. See methodology.
