Color Vision Deficiency (CVD) affects nearly 8% of men and 0.5% of women worldwide. Existing color correction methods often rely on prior clinical diagnosis and static filtering, making them less effective for users with mild or moderate CVD. In this paper, we introduce Hue4U, a personalized, real-time color correction system in Augmented Reality using consumer-grade Meta Quest headsets. Unlike previous methods, our Hue4U requires no prior medical diagnosis and adapts to the user in real time. A user study with 10 participants showed notable improvements in their ability to distinguish colours. The results demonstrated large effect sizes (Cohen’s \(d > 1.4\) ), suggesting clinically meaningful gains for individuals with CVD. These findings highlight the potential of personalized AR interventions to improve visual accessibility and quality of life for people affected by CVD.
