The following project explores how colored light can be used as a variable to manipulate the perception of a surface pattern. Placing the work within the textile design field, colors are a main factor for the development, it shows that colors’ visual state changes when colored light is inflicted. Taking advantage of the effect, an aim was set to explore the relationship between colored light and colored surface to expand methods of designing dynamic and storytelling surface patterns. This to add a different approach of how patterns can be created with a motion ability. The method used was through experimenting with different color combinations under colored light, observing movement of different color placements combined with motif arrangements and patterns, in order to find a working effect. The outcome are three different surface patterns with a dynamic property, each with its own storytelling aspect narrated by the colored light changing. This contributes to a playful way of creating depth to surface patterns, which can be developed further to different textile areas.

Examensarbetet genomfördes vid Jönköping University i samband med Ljusdesign utbildningen år 2017. Undersökningen avsåg att undersöka trafikmiljön utmed motorvägen mellan Värnamo och Jönköping, för att kunna kartlägga och få en uppfattning av hur effektbelysningen där kan användas med färgat ljus utan att skapa en fara i trafiken. Målet var att undersöka om effektbelysningarna visade en påverkan på bilförarnas upplevelse av motorvägen, samt om färgerna gav en skillnad i upplevelsen eller skapade distraktioner. Området var aktuellt att undersöka eftersom effektbelysningar utmed vägar blir alltmer vanliga efter teknologin inom belysning blivit mer användbar och ekonomiskt försvarbar. Av det skälet blir effektbelysningar av färg vanliga men antas också ge en påverkan i trafiken som vi inte är medvetna om. Studiens frågeställningar formulerades därefter och undersökte hur effektbelysning på objekt påverkar bilförares upplevelse i trafiken. Samt om effektbelysning av färg och neutralt ljus påverkade upplevelsen olika.Fältstudien genomfördes under tre kvällar i mars månad på en bensinstation i anknytning till sträckan som undersöktes. Deltagarna svarade på ett frågeformulär med semantiska skalor där de fyllde i hur de känt sig och upplevt vägsträckan de hade kört. Av deltagarna tillfrågades slumpmässiga uttagna personer om de kunde svara på följdfrågor i form av en intervju. På sträckan fanns sju stycken effektbelysningar varav tre hade färgat ljus. Resultaten visade att effektbelysningen på objekten fångade bilförarnas uppmärksamhet och påverkade bilförarnas upplevelse av vägsträckan. Studien visade även att förarna påverkades olika av effektbelysningarna beroende på om ljussättningen var av färgat eller neutralt ljus. Slutsatserna av undersökningen visar hur förarna i denna studie upplevde sträckan mellan Jönköping och Värnamo. För att konstatera hur belysta objekt generellt påverkar trafiksäkerheten krävs mer forskning. / The thesis was conducted at Jönköping University in conjunction with the lighting design education in year 2017. The study aimed at investigating the traffic environment along the high way between Värnamo and Jönköping in order to map and get an idea of how the effect lighting can be used with colored light without creating a danger to traffic. The aim was to investigate whether the effect lights showed an impact on the driver's perception of the highway, and if the colors gave a difference in the experience or created distractions. The area was relevant to investigate as effect lighting are becoming more common after the technology has become more useful and economically justifiable. For that reason effect lighting with color are becoming more common, but are believed to have an impact on traffic that we are not aware of. The thesis questions were then formulated and investigated how effect lighting on objects affects drivers' experience in traffic. As well as if effect lighting of color and neutral light affect drivers’ experience of the road differently.The field study was conducted for three nights in March at a gas station related to the route that was investigated. Participants answered questions with semantic scales where they answered how they felt and experienced the road. Some of the participants were also randomly picked and asked if they could answer any following questions in the form of an interview.The road that was investigated had seven different effect lightings, witch three of them had colored light. The results showed that the lighting on the objects caught the attention of car drivers and affected the road drivers' experience of the road. The study also showed that the drivers were affected differently by the effect lights depending on whether the lighting was of colored or neutral light. The conclusions of the survey show how the drivers in this study experienced the road between Jönköping and Värnamo. To find out how effect lighting on objects generally affect road safety, more research is required.

Recently, there has been a notable rise in the use of colored lighting for both indoor andoutdoor spaces. This trend necessitates a clear understanding of the principles behindselecting lighting levels that are both ergonomic and energy efficient. The objective ofthis study was to establish guidelines for planning colored light. An experiment wasconducted where the perceived brightness of three different near-monochromatic lightswere compared to white light. The stimuli covered a narrow visual field. 33 personsaged 18-40Y participated. Through the measurement of the participants' perception ofthe amount of colored light required -to achieve the same level of brightness as withwhite light- the study was able to determine a percentage-based relationship betweencolored and white light. The result showed that there were clear differences in theperceived brightness of the different colored lights, in line with earlier research withsimilar conditions. This implicates that the results may be used as a foundation whenplanning colored light.

This thesis is about the multicolored gradients seen when using certain dichroic color lters with artificial light. As of now, this phenomenon lacks a unambiguous descriptor, and “Goniochromatic Gradient” is proposed. With help of optical physics, the science of color vision and information about dichroic products, principles for the relationship between goniochromatic gradients and dichroic filters are formulated for anyone interested in exploring this visual phenomenon.
