# 🎨 ColorBench
[**📖 Paper**](https://arxiv.org/abs/2504.10514) | [**💻 GitHub**](https://github.com/tianyi-lab/ColorBench)
ColorBench is a **multimodal dataset** to comprehensively assess capabilities of VLMs in color understanding, including color perception, reasoning, and robustness, introduced in ["ColorBench: Can VLMs See and Understand the Colorful World? A Comprehensive Benchmark for Color Perception, Reasoning, and Robustness"](https://arxiv.org/abs/2504.10514).
It provides:
- **More than 5,800 image-text questions** covering diverse application scenarios and practical challenges for VLMs evaluation.
- **3 categories and 11 tasks** for various color-centric capabilities evaluation including Perception (Color Recognition, Color Extraction and Object Recognition), Reasoning (Color Proportion, Color Comparison, Color Counting, and more) and Robustness.
## 📃 Instruction
The data/test*.parquet files contain the dataset annotations and images pre-loaded for processing with HF Datasets.
```bash
from datasets import load_dataset
color_bench = load_dataset("umd-zhou-lab/ColorBench")
```
