Under warm 2700K interior light Cumulus shifts subtly: takes on a orange cast, gains intensity; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 2.2), so it is a lighting-stable choice.

Against white it measures 1.12:1 and against black 18.77:1, so black text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid white text on this color entirely.
One color explored: close hues with real lightness and chroma structure, so the palette is the anchor through value rather than a set of colors.
#f3f3e6 · #cacabe · #a3a398 · #7d7d74 · #5a5a52 · #383832
The anchor's neighbours on the wheel — everything shares an undertone, so the chord carries color without anything having to be muted to get along.
#f3f3e6 · #f0dda8 · #e6c599 · #d8ae8e · #c79986 · #b4857f
The mid-gap pairing — sage and mustard, terracotta and olive. A foil rotated 40–65° toward warm or cool: too far to be kin, too near to argue, carried by temperature and a deliberate value offset.
#f3f3e6 · #9eb9a9 · #979567 · #4c8264 · #5c5b32 · #2a4435
One deliberately opposed voice — a single restrained counterpoint across the wheel, or temperature against temperature where the anchor is too muted to carry a loud opposite.
#f3f3e6 · #cfcfbf · #aead8f · #8c8b71 · #625f8e · #2f2f20
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f3f3e6 · #d4d3db · #95958b · #59595e · #26251b · #010102
This color as a ground rather than a subject — its own restraint held across a narrow value band, carrying one saturated voice from the opposite temperature.
#f3f3e6 · #c9c9c4 · #9c9c96 · #23231b · #040401 · #cfca4e
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#f3f3e6 · #d3d3e3 · #9190b8 · #565382 · #231f42 · #010100
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f3f3e6 · #d3d3e3 · #7d96ba · #6a4c75 · #0e2543 · #030004
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f3f3e6 · #c6d8e0 · #6c9db1 · #784862 · #3a162b · #00050b
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#C6C6BA · #9A9A90 · #717168 · #4A4A43 · #272621
Its high lightness and low chroma make it a natural background or large-surface color. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
