What Color Scheme is More Effective in Assisting Readers to Locate Information in a Color-Coded Article?
Ho Yin Ng, Zeyu He, Ting-Hao 'Kenneth' Huang

TL;DR
This study evaluates how different color schemes in LLM-coded documents affect users' ability to locate information, finding that certain schemes improve performance and user preference.
Contribution
It provides empirical evidence on the impact of specific color schemes on information retrieval effectiveness in LLM-annotated texts.
Findings
Non-analogous color schemes enhance search performance.
Yellow-inclusive schemes are more preferred by users.
Color choice significantly influences information-seeking efficiency.
Abstract
Color coding, a technique assigning specific colors to cluster information types, has proven advantages in aiding human cognitive activities, especially reading and comprehension. The rise of Large Language Models (LLMs) has streamlined document coding, enabling simple automatic text labeling with various schemes. This has the potential to make color-coding more accessible and benefit more users. However, the impact of color choice on information seeking is understudied. We conducted a user study assessing various color schemes' effectiveness in LLM-coded text documents, standardizing contrast ratios to approximately 5.55:1 across schemes. Participants performed timed information-seeking tasks in color-coded scholarly abstracts. Results showed non-analogous and yellow-inclusive color schemes improved performance, with the latter also being more preferred by participants. These findings…
