Applying Color Tones in Workplace: A Case Study of Chulalongkorn University’s Faculty of Engineering

Abstract

This research investigated the association between adjusted color tones (value and intensity) and keywords representing positive workplace ambience. The aim was to select colors aligning with visual ergonomics in the workplace principles for the renovation of offices within Chulalongkorn University's Faculty of Engineering, specifically the Finance and Procurement, Academic Affairs, and Physical Plant and Archives departments.  Ninety-two percent of the main user group were divided into three groups based on department and surveyed to rank keywords representing positive work ambience. The top three keywords from each group were then associated with 70 color swatches under the same lighting conditions as the actual workspace. Analysis of the selected color tones revealed that almost all exhibited high value and low intensity, aligning with visual ergonomics in the workplace principles for large, continuous surfaces, minimizing visual fatigue.  Discussion highlighted the association of multiple light and muted colors with a single keyword, and some tones' association with multiple keywords. This deviated from universal color meanings and findings in previous research.  The findings suggest that any color with a value and intensity not exceeding 30 on the NCS standard color system is suitable for workplaces prioritizing visual comfort, relaxation, cleanliness, or all three. The findings provide a guideline for the application of color tones in the workplace where color is a key consideration.  Further research should explore associations between all keywords and color tones, expand color palette detail, or compare results with other public and private sector populations to further validate these findings.
