Morphology
The meaning is directly compositional: 'spectral' (= pertaining to a spectrum) modifies 'color', so a learner who knows both words can infer it refers to a color from the spectrum (i.e., associated with a single wavelength). Although the term is somewhat technical, its sense follows regular modifier+noun composition and is therefore transparently derivable from the parts.
Etymology
Spectral color comes from the image of a glass prism or a rainbow splitting white light into separate bands of color. Each band is one spectral color, light of a 'single wavelength' rather than a mix, so the term means a pure color.
