Indoor lighting quality: Effects of different wall colours
2016
This paper reports the results of measurements performed in a test room to investigate the impact of using different wall colours and light scenes on indoor lighting quality. Eye level spectral irradiances were measured for a user located inside the room and seated at a desk. These measurements allow the use of the Irradiance Toolbox, which makes it possible to calculate equivalent illuminances for the photopigments in the human eye. Moreover, the CIECAM02 colour appearance model was used to investigate the variations in hue and chroma values of the different wall colours when changing the light scene. The results demonstrate that there are significant variations in eye level spectral irra…
Kultūras atšķirības patērētāju uzvedībā Latvijā un Uzbekistānā, krāsu mārketings
2018
Krāsa ir neatņemama cilvēka dzīves sastāvdaļa, tā ietekmē zemapziņas līmeni. Krāsu katrā kultūrā var raksturot citādāk un tās ietekmē dažādus mūsu dzīves aspektus. Produkta pārdošanā krāsas izvēlei ir liela nozīme. Tirgotāji bieži izmanto krāsu kā priekšrocību tirgū. Neuromārketings pēta kā personas uztver krāsas. Viens no krāsu uztveres faktoriem ir kultūra. Katrā kultūrā krāsu izpratne ir citāda un tādēļ grūti ir izveidot produkta dizainu. Krāsām dažādās valstīs var būt atšķirīgas nozīmes. Tirgotāji izmanto krāsu kā vienu no galvenajiem mārketinga stratēģijas faktoriem. Šī bakalaura darba autors raksturo krāsu uztveres atšķirības Latvijas un Uzbekistānas kultūrās kā mārketinga līdzekli pr…
Ultraviolet reflectance of male nuptial colouration in sand lizards (Lacerta agilis) from the Pyrenees
2007
Abstract The evolutionary significance of lacertid colourations is relatively unexplored. However, several studies have demonstrated signalling by means of bright green colouration in Swedish Lacerta agilis males during the breeding season. Unfortunately, most of these studies have been based on human colour perception that differs in several ways from that of lizard. An important difference between human and lizard colour vision is the presence of an ultraviolet (UV) sensitive cone in lizards. The available evidence suggests that male sand lizards colorations do not reflect UV wavelengths, at least in Swedish populations. However, this study, based on objective (spectrophotometric) measur…
