Physiology color score extracted from pictures taken during a thermal stress experiment using reef building corals collected in Kāne'ohe Bay, O'ahu, Hawai'i.

Understanding the response of the coral holobiont to environmental change is crucial to inform conservation efforts. The most pressing problem is “coral bleaching,” usually precipitated by prolonged thermal stress. This dataset spans a five week thermal stress experiment in which images were taken of coral individuals and analyzed for a "color score".解析珊瑚共生体（coral holobiont）对环境变化的响应，对指导珊瑚保护实践至关重要。当前最为严峻的问题当属珊瑚白化（coral bleaching），其通常由长期热应激诱发。本数据集涵盖一项为期五周的热应激实验，实验期间对各珊瑚个体进行成像拍摄，并通过图像分析获取其色彩评分（color score）。
