spectral + noun (analysis, data, colour, line, pattern)

Always used before a noun in scientific and technical contexts. Not to be confused with sense 1 — the two meanings come from different historical roots (Latin spectrum 'appearance' vs spectre 'ghost'), even though both are spelled spectral.

❌The party had spectral decorations.
✅The party had colourful decorations.
💡spectral refers to the scientific light spectrum, not to general brightness or colourfulness.
