Quantifying colour appearance. part IV. Transmissive media

Quantifying colour appearance. part IV. Transmissive media The experimental data from this study extends the LUTCHI colour‐appearance data to cover transmissive media. Two further experiments were carried out: one used a large cut‐sheet transparency viewed using a back‐lit illuminator, and another used a 35‐mm slide projected onto a white screen. These new data were used to reveal the changes in colour appearance caused by different viewing parameters studied, and to evaluate the predictive accuracy of five uniform colour spaces and colour‐appearance models. The results show that Hunt's 91 model (developed to fit earlier experimental results) did not perform as well as it did in the previous studies using nontransmissive media. This implies that there are large differences in perceived colour appearance between transmissive and nontransmissive media viewing conditions. Some modifications were subsequently made to Hunt's 91 model and the predictive accuracy was greatly improved. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Color Research & Application Wiley

Abstract

The experimental data from this study extends the LUTCHI colour‐appearance data to cover transmissive media. Two further experiments were carried out: one used a large cut‐sheet transparency viewed using a back‐lit illuminator, and another used a 35‐mm slide projected onto a white screen. These new data were used to reveal the changes in colour appearance caused by different viewing parameters studied, and to evaluate the predictive accuracy of five uniform colour spaces and colour‐appearance models. The results show that Hunt's 91 model (developed to fit earlier experimental results) did not perform as well as it did in the previous studies using nontransmissive media. This implies that there are large differences in perceived colour appearance between transmissive and nontransmissive media viewing conditions. Some modifications were subsequently made to Hunt's 91 model and the predictive accuracy was greatly improved.
