Under warm 2700K interior light Indigo shifts subtly: leans toward magenta; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.4), so it is a lighting-stable choice.

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.
#ab8adc · #8760bd · #66359d · #4b0082 · #20003e · #04000f
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.
#3a4fa5 · #453097 · #4b0082 · #420053 · #33002d · #210011
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.
#dc90af · #9c74d4 · #b73276 · #773b56 · #4b0082 · #2c0050
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.
#b2d538 · #7e67a0 · #5a4e6e · #4b0082 · #260a42 · #0a0019
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#eff5e2 · #bcb3cc · #808477 · #544a64 · #4b0082 · #1f2414
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.
#f0f4e8 · #c7cbbe · #999e8f · #202512 · #020400 · #4b0082
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d8dab4 · #d5a1cc · #2eac66 · #414c38 · #4b0082 · #000b35
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#dbd9b3 · #74c183 · #917d54 · #464c3d · #4b0082 · #05092e
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffeee1 · #f9a14d · #009786 · #005d52 · #4b0082 · #351900
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.
