Educational possibilities of the project Colour visualization of music
Bojan Klemenc, Peter Ciuha, Franc Solina, 2011, original scientific article

Abstract: We propose a system of colour visualization of music based on a system of colour signs, which are connected to musical tones. Tones, which are in harmonic relationships, are represented by related colours. First, we outline the foundations on which the system of colour signs is based - the mathematical model of harmony. We discuss several possibilities of visual representation of expressive elements of music - melody, composition, rhythm and harmony. These relationships enabled us to develop a computer program that employs these elements for visualization. The program mimics human perception in which the parts are determined by the perception of the whole. Furthermore, the program enables the development of tools that can enhance music understanding during listening or performing. Music performance can acquire a new quality with the use of interactive coloured musical instruments, which by using colours show the performer different possibilities for forming musical harmonies and thereby change the composing of music into a game and attractive colour-aural journey. Here we stumble upon a challenge for educational science and methodology: how to use such upcoming multimedia tools. These tools would bring the processes of learning and playing a game closer together since playing games is a child's most natural form of functioning. Furthermore, in the area of artistic creation we can once again establish a balance between our logical and intuitive nature.

Periodic colour model
Vojko Pogačar, 2012, original scientific article

Abstract: This article is based on the thesis that natural cycles have an ontological influence on our symbolic meaning system and classification of notions. Lately, these symbolic meanings have passed over to colour meanings along with the evolution of a visual system. Colours are one kind of human convention, used unconsciously in every day communication. At the macroscopic level, sunlight is the only source of light which defines those natural daily-and annual-cycles. These two cycle systems symbolically correspond with two basic geometric sequences of colour palettes, forming major- and minor-angled colour circle lines. Inserted into the Periodic Colour Model they explain the logic of dominant colours and the relationships among them at the specific cross-section of periods. In the Periodic Colour Model, all three dimensions of colour are summarised, including time in a common model which represents a complex analytical and prognostic tool based on symbolic values transmitted from natural cycles.

Bottle model of colour vision with the colour brown as an example
Matej Erjavec, Nataša Vaupotič, 2006, original scientific article

Abstract: In this paper, a model to teach colour vision is presented. Three different types of the cones that enable colour vision are visualized as bottles, and the amount the different bottles are filled is associated with the appearance of colour that is formed by the brain. It is shown that the appearance of colour depends both on the relative and the absolute filling of the bottles. We focus on the spectral composition of light reflected from brown surfaces and show that when we see brown, there is usually red, yellow, orange and green light falling into our eyes, but of low intensity. The same spectral composition of the incident light would give the impression of orange colour if the intensity of light were higher.
