An evaluative study on perceived colour measurement method in architecture using tablet devices

Abstract

When we think of colour experience in architecture, the judgement of perceived colour, which is affected by the human perceptual system, is critically important because the goal of architectural design is to construct the human-centric environment. However, recording observers’ judgement of the perceived colour is not always easy in field surveys. Recently, several methods have been developed to measure perceived colour. In this study we propose to use portable tablet devices in consideration of its easiness to carry and use in the actual architectural field survey. The validity of the method using portable tablet devices to judge perceived colour is verified by comparing its performance with that of the conventional colour matching method, with the help of colour charts. Experimental results show that the proposed method has sufficient validity for the judgement of perceived colour in spaces under sufficient light by matching the correlated colour temperature on the tablet display to that of the surrounding light.
