#000B44Storm (#000B44) is a very dark, soft blue with an OKLCH hue of 264°, lightness 0.2 and chroma 0.107. It sits on the cool side of the color wheel. In practice it behaves as a grounding tone — suited to text, outlines, and shadowed surfaces.

Under warm 2700K interior light Storm shifts subtly: leans toward purple; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1), so it is a lighting-stable choice.

Against white it measures 18.56:1 and against black 1.13:1, 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.
#879ac0 · #5f74a0 · #395080 · #172e61 · #000b44 · #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.
#005d61 · #004a58 · #00374d · #002443 · #000b44 · #060029
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.
#ac92b6 · #657eb2 · #794d8b · #2d4577 · #37243f · #000b44
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.
#e5be70 · #606b81 · #3d4c69 · #272f40 · #000b44 · #000013
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f7f1e7 · #b4bbc9 · #8a877f · #4f5765 · #2e2a21 · #000b44
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 · #a8a092 · #362d1b · #140b00 · #000b44
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d5dab4 · #ea8d2f · #8c72ae · #714742 · #2b1a4f · #000b44
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#fcf1da · #e7ac87 · #878e3b · #7d4720 · #2a2d0a · #000b44
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffedeb · #eda6a1 · #5d985c · #346334 · #411f1d · #000b44
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.
