Morphology
spectral = spectrum (transparent) = spectr + al
This is a regular Latinate adjective formation from the stem spectr- and the suffix -al, so the meaning is readily recoverable from the base word spectrum.
Etymology
Spectral comes from the Latin root spec- meaning 'to look' and from the related word spectrum, which names the range of light colors. So spectral often means 'relating to a spectrum' or to the light and colors that instruments measure.
