Under warm 2700K interior light Epic Blue 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 ≈ 2.5), so it is a lighting-stable choice.

Against white it measures 5.08:1 and against black 4.14:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text.
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.
#a6c9ff · #649fff · #0066ee · #004ebb · #00307a · #001441
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.
#00a3d3 · #008ad5 · #0066ee · #4748d0 · #562cab · #581283
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.
#d388ff · #a57bc0 · #0066ee · #004cb7 · #003382 · #34024a
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.
#fdb500 · #7a93bb · #0066ee · #265094 · #0d326c · #03183d
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#fdf0db · #7c8da7 · #0066ee · #5f5649 · #14243d · #0f0600
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 · #d2cbbf · #aaa193 · #392e1d · #170d00 · #0066ee
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#fff0d7 · #b68100 · #0066ee · #745000 · #322000 · #000013
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#fff0d7 · #da6500 · #0066ee · #5c5c00 · #3e1700 · #040300
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffedec · #e2555e · #0066ee · #1e6a00 · #062d00 · #160001
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#2C6CD4 · #4270BA · #5572A0
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.
