Under warm 2700K interior light Space Dust shifts subtly: leans toward purple, loses intensity; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.8), so it is a lighting-stable choice.

Against white it measures 12.43:1 and against black 1.69:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid black 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.
#6f97ec · #446fce · #1b46b0 · #002299 · #00004e · #000012
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.
#006184 · #004b7f · #002299 · #24007a · #23004c · #1a0028
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.
#c597d9 · #5b88e9 · #9840b8 · #674176 · #002299 · #00036b
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.
#f7b900 · #5874ad · #455576 · #002299 · #03164e · #00031f
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#faf1de · #acb9d2 · #898275 · #43506a · #002299 · #292110
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.
#f7f1e6 · #d1cbbe · #a8a193 · #372e1c · #150c00 · #002299
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#c6debe · #c4c536 · #9269a3 · #41533c · #002299 · #051219
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#fff0d3 · #ff9d58 · #828b00 · #7d3c00 · #002299 · #222500
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffedeb · #ff9791 · #139e24 · #00620d · #002299 · #460309
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

As a deep tone it works for grounding elements — text, outlines, and shadowed surfaces — rather than open fields. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
