20.500.12556/RUL-103036 Vpliv osvetlitve na zaznavanje barv in njihov simbolni pomen Influence of light on colour perception and symbolic value of colours Ljudje so stalno izpostavljeni različnim vrstam svetlob in obkroženi z mnogo barvnimi odtenki – to se dojema kot nekaj vsakdanjega. Vprašanje pa je, ali različna svetloba vpliva na človekovo dojemanje barve in ali lahko svetloba na barvo vpliva do take mere, da se spremeni način našega zaznavanja in opisovanja. Znano je, da ima vsaka barva več simbolnih pomenov. Namen diplomskega dela je bil preučiti, ali svetloba vpliva na spremenjen simbolni pomen modre barve, kako se modri odtenki pod svetlobo sploh spremenijo in kako opazovalci to zaznajo. Izbranih je bilo 12 vzorcev modre barve z različnim barvnim tonom, nasičenostjo in svetlostjo. Testne osebe so vzorce opazovale v svetlobni kabini pod večerno svetlobo A, standardno dnevno svetlobo D65 in hladno fluorescenčno svetlobo F2. Vsi vzorci so bili nato še izmerjeni s spektrofotometrom. Analiza je bila narejena na podlagi ankete in rezultatov meritev. Rezultati so pokazali, da hladna svetloba barvo naredi hladnejšo in pod toplo svetlobo barva deluje toplejša. Zaradi spremembe v osvetlitvi se videz barve spremeni, prav tako njeni osnovni parametri: barvni ton, nasičenost in svetlost. Sprememba barve, do katere pride zaradi spremenjene osvetlitve, povzroči tudi spremembo v čustvenem odzivu opazovalca in simbolnem pomenu barve. Ugotovitve kažejo, da osnovni parametri barve ne vplivajo na to, ali in kako se bo spremenil odziv opazovalcev ob spremembi osvetlitve. People are constantly exposed to different types of light and are surrounded by many hues which is perceived as something ordinary. The question is, whether or not different types of light have any impact on human perception of colour and whether light can affect colour to such an extent that it changes our perception and description. It is a known fact that every colour has several symbolic meanings. The aim of the diploma thesis is to study whether light affects the changed symbolic significance of blue, how blue hues change under the light and how observers perceive this. 12 samples of blue were chosen, each differing in its tone, saturation and lightness. The candidates observed them in the colour viewing light booth under the standard lightlight illuminant A, standard daylight illuminant D65 and cool fluorescent illuminant F2. All samples were then measured with spectrophotometer. In the analysis part of the thesis the results of the testing and the results of the measuring were combined in the complete analysis of blue hues under each illuminant. The results show that the cold illuminant makes the colour colder, while the warm one makes it warmer. The change of the illuminant causes the difference in colour and its parameters: hue, saturation and lightness. A change in the colour, resulting from changed illumination, also results in the change of the emotional response of the observer and the symbolic meaning of the colour. The findings show that the basic colour parameters do not affect whether or how the response of the observers will change when the illumination changes. svetloba zaznavanje barv simbolna vrednost barve barvni ton nasičenost svetlost light colour perception symbols hue saturation lightness true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2018-09-13 07:46:54 2018-09-13 07:47:00 2022-08-16 03:39:37 0000-00-00 00:00:00 2018 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 64043 2753.pdf 2753.pdf 1 4406B262D85D33524DF257AC61F7FE67 f65ecf57d4c95842e0cb5ce50eb808590cc0d5bd01da8648e083977f9d54fda8 b163276b-a1b5-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=113419 Naravoslovnotehniška fakulteta 0 0 0
