Abstract:

Colour carries a psychologically relevant meaning, and the colours we see affect our psychological performance. Colour-coding impacts learners’ cognitive processing as material-oriented interventions in multimedia learning. For educational purposes, colours can be used to stimulate neural activity, allowing pupils to learn, memorize, and retain new information more efficiently. Especially for those who are visual learners, the brighter the colours are, the more they are able to capture the attention for particular types of information. (Elliot and Maier: 2012).

Abstract:

Abstract Colour laser marking is a contemporary method for adding colours onto metal surfaces, suitable for creating logos, barcodes, metal crafts, and jewelry. This study focused on colour laser marking on the biomedical alloy Ti6Al4V (TC4), examining how different colours manifest on its surface. Power settings ranged from 9 W to 18 W, while frequencies spanned 500 kHz to 2000 kHz. The research investigated how altering laser frequency and defocus distance influenced colour variation. Surface features were assessed using 3D optical microscopy, revealing texture and roughness traits. Results

The increasing interest in the use of a wide range of colours in buildings, especially dark colours, may lead to the early degradation of the façades, compromising their aesthetic and thermal performance. On the other hand, the incorporation of nanopigments with high reflectance properties can contribute to reducing the absorption of solar radiation. The nanoparticles contribute to increasing the solar reflectance of coatings, decreasing the surface temperature and improving the coating performance.

ABSTRACTHow well can a bird discriminate between two red berries on a green background? The absolute threshold of colour discrimination is set by photoreceptor noise, but animals do not perform at this threshold; their performance can depend on additional factors. In humans and zebra finches, discrimination thresholds for colour stimuli depend on background colour, and thus the adaptive state of the visual system. We have tested how well chickens can discriminate shades of orange or green presented on orange or green backgrounds. Chickens discriminated slightly smaller colour differences betwe

Abstract In the present study, we focus on the priming effect of colour on mitigating the attentional reorientation cost, which is led by re-constructing the frame of reference for attention shift and visual search in sequential presentations of temporal data visualization. The study involves two experiments using complementary recordings of behavioural performance and eye-tracking events. Two aspects of colour primes are highlighted: the prime validity and the colour perceptual accessibility. A task paradigm integrating the feature search and keeping-track task was adopted in our experiments.

Abstract:

Within (and between) cultures, people tend to agree on which parts of colour space are easiest to name and what the names for these regions are. Therefore it is likely that the manipulation of ease of naming (nameability) of colours should change performance in tasks where categorisation by colour name is important. More specifically, highly ‘nameable’ colour sets should lead to better performance than metrically equivalent but less categorically distinct sets, when the task requires categorisation. This hypothesis was investigated by testing observers on a name-based task, the naming and subs

Abstract:

One of the factors that affect the colour quality of the platy fish (Xyphophorus helleri) during cultivation is the environment in bright light conditions, where setting bright light conditions can be done using a tank with a colour that can absorb light. Therefore, a study was conducted to examine the effect of tank colour on improving the colour quality of the platy fish and determining the correct tank colour. This research was conducted with an experimental method using a completely randomized design (CRD) consisting of five treatments repeated three times. The colour treatments of the tan

Abstract:

In one of the most common forms of synaesthesia, linguistic–colour synaesthesia, colour is induced by stimuli such as numbers, letters, days of the week, and months of the year. It is not clear, however, whether linguistic–colour synaesthesia is determined more by higher level semantic information—that is, word meaning—or by lower level grapheme or phoneme structure. To explore this issue, we tested whether colour is consistently induced by grapheme or phoneme form or word meaning in bilingual and trilingual linguistic–colour synaesthetes. We reasoned that if the induced colour was related to

Abstract:

Although Frank Stella intended to create flat, illusion-less Irregular Polygons paintings, it is not uncommon to experience the illusion of colour depth, based on the interaction between their fluorescent and conventional colours. Some critics praised these artworks’ flatness, while others described odd depth experiences that they categorised as a new kind of illusion. In order to provide a correct reading of these works and to reassess their art historical significance, a scientific case study regarding this colour-depth effect imposes itself. This article discusses an experiment in which we

Abstract Colours play an important role in many applications such as in education, communication, tourism, marketing, and architecture. From the previous research, especially related to education, colour could affect people’s focus or attention level. However, with further investigation, the colour could also be used for controlling or activating electronic devices. Therefore, the purpose of this study is to find out if turquoise, green, red, and a combination of red, orange, and yellow (picture of autumn) could trigger the attention level to be equal to or above the attention threshold.

Abstract:

The effect of spectral composition of white light sources with variable chromaticity on objective and subjective evaluations of their colour rendering was studied. The dependences of the colour rendering indices on colour temperature were obtained for four light sources: a tungsten halogen lamp, white light emitting diodes with adjustable correlated colour temperature, fluorescent lamps of three colours, and three-colour light emitting diodes. The dependences of general colour rendering index (CRI) Ra and Smet’s memory colour rendering index (MCRI) Rm on the distance uv between a point corres

Abstract:

The inducing effect of blue in colour assimilation on a CRT screen is so strong that pale blue apparently veils the stimulus pattern (Miyamoto and Hasegawa, 1996 Perception25 Supplement, 105). A similar tendency can be observed on painted paper, but this effect is not so marked. This led us to try colour matching between coloured papers and colours reproduced on a CRT screen. In both conditions the shapes (square) and the sizes (35 cm × 35 cm) were the same. They were displayed in the centre of a 155 cm × 155 cm gray (Munsell value 5, 22 cd cm−2) square with 10 cm wide white fringe (74 cd cm−2

Abstract:

The heat treatment of softwood (i.e. spruce, pine, fir, and larch) may result in significant colour changes. During this study Scots pine and spruce samples were steamed and analysed for their altered hue and lightness. Treatments included: 0 to 22 days of steaming time at a temperature range of 70 to 100°C. The outcome included a variety of colours between the initial hues and brownish tint. These new colours are similar to that of aged furniture and indoor wooden structures. Consequently, properly steamed softwood may be used to repair historical artefacts and relic furniture.

Colour is the most enriched and endless form of human life. It reflects our mood and more importantly, it has more influence and effect on our lives than we realize. How can we define colour, a reality, a feeling that creates energy, enthusiasm, potential, anger, affection, passion andmany other feelings in us. If we are in pleasant feeling, colour fills us with the feel of joy and happiness and in contrary to this if we are unhappy and sad the colours are there, who fill with the feel of unhealthy, unhappiness and sadness. Now it is a matter to think upon that why we correlate our feelings wi

The landscape, bearing certain pressure from the society, simultaneously has an aesthetic potential and actively affects the emotional and psychological comfort of a person. Among the many factors affecting the aesthetic qualities of the landscape (relief, vegetation, water, etc.), colour is also separated. The color diversity of the landscapes is impossible to appreciate with only using eyes. The article presents a unique methodology for separating colour shades, which are one of the important aesthetic factors of the landscape.

Abstract:

We present data on colour generalisation by chicks relevant to Tenenbaum and Griffiths' (T&G) Bayesian framework. Chicks were trained with either one or two colours, and tested for interpolation and extrapolation. T&G's framework predicts an observed lack of extrapolation on the red to yellow line in colour space. A modification incorporating stimulus uncertainty deals with a prototype effect, where an intermediate is preferred to exemplars. After training to complementary colours, chicks do not generalise across an intermediate grey as T&G predict. [Tenenbaum & Griffiths]
