Lights, Camera, Malfunction: When Illumination Robustness Leaves VLA Models Blind to Color

Lights, Camera, Malfunction: When Illumination Robustness Leaves VLA Models Blind to Color

Summary

This research paper introduces FLARE, a framework demonstrating how targeted illumination can disrupt Vision-Language-Action (VLA) models. The authors identify that standard adversarial training often leads models to ignore color as noise, degrading performance on color-dependent tasks. They propose ChromaGuard, a chroma-preserving adversarial training method tested on a physical 6-DoF robotic platform using SmolVLA, which achieves 95.0% success in benign tasks and 88.8% under attack, compared to a maximum of 48.8% for naively defended models.

Editorial context

The study identifies a specific vulnerability in Vision-Language-Action models where naive data augmentation causes them to discard color information, leading to significant performance drops on real-world tasks; the authors propose ChromaGuard, an adversarial training method that preserves chromatic cues to maintain high success rates under both benign and attacked conditions.
