Humans like some colours and dislike others, but which particular colours and why remains to be understood. Empirical studies on colour preferences generally targeted most preferred colours, but rarely least preferred (disliked) colours. In addition, findings are often based on general colour preferences leaving open the question whether results generalise to specific objects. Here, 88 participants selected the colours they preferred most and least for three context conditions (general, interior walls, t-shirt) using a high-precision colour picker. Participants also indicated whether they associated their colour choice to a valenced object or concept. The chosen colours varied widely between individuals and contexts and so did the reasons for their choices. Consistent patterns also emerged, as most preferred colours in general were more chromatic, while for walls they were lighter and for t-shirts they were darker and less chromatic compared to least preferred colours. This meant that general colour preferences could not explain object specific colour preferences. Measures of the selection process further revealed that, compared to most preferred colours, least preferred colours were chosen more quickly and were less often linked to valenced objects or concepts. The high intra- and inter-individual variability in this and previous reports furthers our understanding that colour preferences are determined by subjective experiences and that most and least preferred colours are not processed equally.

Popular opinion holds that color has specific affective meaning. Brighter, more chromatic, and warm colors were conceptually linked to positive stimuli and darker, less chromatic, and cool colors to negative stimuli. Whether such systematic color associations exist with actually mood felt remains to be tested. We experimentally induced four moods—joy, relaxation, fear, and sadness—in a between‐subject design (N = 96). Subsequently, we asked participants to select a color, from an unrestricted sample, best representing their current mood. Color choices differed between moods on hue, lightness, and chroma. Yellow hues were systematically associated with joy while yellow‐green hues with relaxation. Lighter colors were matched to joy and relaxation (positive moods) than fear and sadness (negative moods). Most chromatic colors were matched to joy, then relaxation, fear, and sadness. We conclude that color choices represent felt mood to some extent, after accounting for a relatively low specificity for color‐mood associations.

Gratitude may act positively on QoL and may protect against psychological distress in the palliative situation. The next step will be the adaptation and implementation of a gratitude-based intervention.

Objectives Posttraumatic growth (PTG) refers to positive psychological changes resulting from individuals’ inner struggles with traumatic events such as life-threatening illness. Although palliative care patients are confronted with their own mortality, little is known about their PTG experience. This study investigates whether PTG is an empirically relevant concept for palliative patients by assessing the prevalence and areas of growth, and examining associations with psychological distress and quality of life. Methods Participants were recruited in Switzerland. Using validated questionnaires, we assessed PTG (Posttraumatic Growth Inventory, PTGI), psychological distress (Hospital Anxiety and Depression Scale), and quality of life (McGill-Quality of Life Questionnaire – Revised). We performed descriptive analyses, Spearman correlations, and linear regressions. Results Fifty-five patients completed the PTGI, 44% of whom experienced no/low growth, 47% moderate growth, and 9% high/very high growth. Participants experienced the greatest positive changes in terms of appreciating life and relating to others. We found significant negative bivariate correlations between PTG and psychological distress (r = −0.33) and between PTG and depression (r = −0.47). Linear regressions showed that PTG is associated with depression (β = −0.468; p = 0.000), but not with anxiety or quality of life (adjusted R2 = 0.219). Significance of results Over half of our patients experienced moderate to very high growth, indicating that PTG is an empirically relevant psychological process in palliative care. PTG is associated with lower levels of depression, possibly as those experiencing growth are more able to process past traumas and build a more positive outlook on one's life and self. By contrast, the relative independence of anxiety and PTG points to the likely coexistence of positive and negative psychological responses to trauma. The lack of association between PTG and quality of life points to the uniqueness of the PTG concept in capturing how people access deeper meaning and greater appreciation of life along the path toward posttraumatic self-reconstruction.
