Comparing Research on the Colour Temperature and Colour Rendering of the Gallery Surface Material's Reflected Light

摘要

As to fine art museum that exhibits big wall works primarily, it is usually difficult to distinguish between gallery lighting and exhibit lighting. The surface material's spectrum information taken by reflected light will influence the artwork's colour perception. This article takes this as cut-in, uses spectrophotometer to measure material's spectral reflectance and calculates the reflected light spectrum according to measured data. The author does the comparation analysis between reflected light's colour temperature and colour rendering of gallery's regular surface materials eg. 56 kinds of stone, 10 kinds of wood and 4 kinds of fiberglas fabric. The conclusions reached by this article have the guidance meaning to the choice of the gallery's surface materials.
