Colour appearance has been extensively studied. It was found that assessing the third dimension of colour appearance, such as chroma, colourfulness or saturation attributes, normally are more inconsistent than for other two dimensions (lightness and hue), even with experienced observers.
Two psychophysical experiments were conducted to address the issue using British and Korean observers respectively. The following word scales to represent the third dimension were scaled by observers: ‘bright’, ‘light-heavy’, ‘active-passive’, ‘fresh-stale’,
‘clean-dirty’, ‘clear’, ‘boring’, ‘intense-weak’, ‘saturated’, ‘vivid-dull’, ‘distinct-indistinct’, ‘full-thin’, and ‘striking’. All observers did not have any colour science background,
nor did they receive any training about each word scale. Predictive models of saturation and of vividness were developed to fit the experimental results. They reflect novice observers' view of colour appearance.

CIC is the premier annual technical gathering for scientists, technologists, and engineers working in the areas of color science and systems, and their application to color imaging. Participants represent disciplines ranging from psychophysics, optical physics, image processing, color science to graphic arts, systems engineering, and hardware and software development. While a broad mix of professional interests is the hallmark of these conferences, the focus is color. CICs traditionally offer two days of short courses followed by three days of technical sessions that include three keynotes, an evening lecture, and a vibrant interactive papers session. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper presentation.
