Why complementary pairs vibrate?

Maximum hue separation can create halation at boundaries — separate complements with white space, typography weight, or neutral buffers.

How is triadic different from split-complementary?

Triadic picks three hues 120° apart; split-complementary offsets the complement by a few steps on each side for slightly softer tension.

Can I use complements only for accents?

Most brands keep 80% neutral and primary, then deploy complements for alerts, links, or illustration pops.

Does colour blindness break complements?

Red-green complements may be indistinguishable for some viewers — validate with the colour-blindness simulator and not colour alone.

Should shadows share complements?

Neutral shadows usually read cleaner; coloured shadows are stylistic and need restraint.

Are wheel relationships device-dependent?

The relationships are mathematical in hue degrees, but display calibration still affects perception.

Can I export harmonised sets?

Copy swatch lists or integrate with the palette generator for fuller token sets.
