Color effects on AI influencers' product recommendations

PurposeThis paper aims to theorize and investigate the use of effective color features in artificial intelligence (AI) influencers, an emerging marketing trend in the social media context. Design/methodology/approachBy analyzing 6,132 pictures posted by ten AI influencers on Instagram, this paper examines the effect of warm colors in AI influencers' social media posts on consumer responses, and how other color features may moderate the effect of warm color. In addition, two experimental studies reveal the underlying process driving the effect of warm color. FindingsWarmer color generated more favorable consumer responses, with brightness significantly moderating the relationship between warm color and favorable consumer responses. Moreover, the results of the experiments establish that perceived warmth and emotional trust mediate the causal effect of warm colors on consumer responses. Research limitations/implicationsThere is still little understanding about consumer perceptions of AI influencers and their acceptance of AI influencers' product recommendations. As such, this research offers theoretical understanding of the color features influencing the effectiveness of recommendations by AI influencers. Practical implicationsBrands have started deploying AI influencers as their brand ambassadors to make product recommendations, representing a new wave of advertising on social media. The findings will thus benefit marketers in developing effective product recommendations using AI influencers. Originality/valueThe present research provides a novel understanding of how visual features, such as color can influence the effectiveness of AI influencers.
