Under warm 2700K interior light Denim 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 ≈ 2), so it is a lighting-stable choice.

Against white it measures 8.25:1 and against black 2.55:1, 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.
#7ba0fb · #5178dd · #2243b6 · #102793 · #040061 · #01001e
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.
#007eae · #0065af · #2243b6 · #3b2898 · #400c76 · #39004e
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.
#c596d4 · #b960d3 · #855c91 · #2243b6 · #122987 · #040863
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.
#f4ba00 · #7790cb · #627192 · #2243b6 · #1c3068 · #0c1838
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#faf1df · #a1acc4 · #706b5e · #2243b6 · #2f3952 · #060300
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.
#f6f1e6 · #d0cabe · #a6a091 · #332b19 · #120900 · #2243b6
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#fff0d1 · #d5a415 · #876600 · #2243b6 · #4b3700 · #010015
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#badbc1 · #b6c275 · #805d3d · #2243b6 · #374435 · #041119
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffedeb · #fc8379 · #008228 · #2243b6 · #004811 · #080000
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

Its chroma is high enough to carry accents, calls to action, and focal moments; large fields of it will dominate a composition. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
