MIXORA CONCEPT
Spectral reflectance
The fraction of incoming light a surface returns at each wavelength.
A reflectance curve describes material color more directly than one RGB triplet. Two different curves can produce a similar display color under one light yet behave differently when mixed or illuminated differently.
What “Strong evidence” means
The core definition or effect is well established across authoritative standards, foundational research or a broad research literature. The label does not make every practical prediction certain.
VISUAL EXPLANATION · MARKER BOARDA sample may reflect little blue light, moderate green and much more red, producing an orange appearance under daylight.
Reflectance is a surface property measured across wavelengths; HEX is a display encoding.
Do we have a measured spectrum, or only a reconstructed estimate from a screen color?
A material that changes reflected or transmitted light through selective absorption and scattering.
