Quantitative colour analyses using digital specification technique for Mármore Bege Bahia, a representative Brazilian ornamental limestone of breccia-like texture

Abstract: ResumoOs autores realizaram ensaios com base em especificações digitais de cores em rocha total e em pontos com o auxílio de scanner, computador e Wilbur, um software original para análises quantitativas de cores, para Mármore Bege Bahia, um calcário ornamental com textura brechóide explotado na região centro-norte da Bahia. Essa rocha é caracterizada pela cor amarela clara (B=83.4), vívida (S=10.8), relativamente homogênea (σ(H)=3.9; σ(B)=6.5), tendendo ligeiramente a cor de laranja (H=35.8). A variação das c… Show more
