VISUAL EVALUATION SAMPLES WITH HIGH CHROMATICITY UNDER THE TWO TYPES OF DAYLIGHT SIMULATORS

Popis výsledku v původním jazyce

Nowadays it is a trend to use high chromacitycolours. These colours are using in many applications such as: warning clothes, fashion design and decorative cosmetics. Many companies were focusing on these colours due to high market potential. Therefore, it is important to study these colours and small differences between these colours.In many cases, the light sources change in LED light source due to it having the ecological and economical aspect. These changes bring lots of problems; discrimination of small colour differences is one among the problems.International Commission on Illumination (CIE) defined a space called CIELAB, which isn’t visual uniform. Based on the previous studies, the data for development and testing of new colour difference formulas and colour spaces are limited in chroma. In this work, we were using high chroma dataset for testing and prediction the performance of known colour difference formulas. For testing, we used grey scale and source emitted daylight simulator (D65) and full spectral LED light source. This work has been compared with visual colour difference form observers and calculated colour difference from spectrophotometer.
