1. **Understanding Hormone Diseases**: Hormone diseases are conditions that arise due to an imbalance or deficiency in hormones produced by the endocrine glands. These can affect various bodily functions and lead to a range of health issues.

2. **Analyzing the Options**:
- **Color Blindness**: This is an inherited disorder related to vision and is not caused by hormonal imbalance. Therefore, it is not a hormone disease.
- **Allergy Disease**: Allergies are immune responses to foreign substances and are not related to hormonal deficiencies. Hence, this is also not a hormone disease.
- **Cretinism**: This condition is caused by a deficiency of thyroid hormones, particularly in newborns. It leads to developmental issues, including reduced memory, feeling cold, and a lower pulse rate. This clearly indicates a hormonal disease.
- **Hemophilia**: This is a genetic disorder affecting blood clotting and is not related to hormone levels. Thus, it is not classified as a hormone disease.

3. **Conclusion**: Among the options provided, Cretinism is the only condition that qualifies as a hormone disease due to its direct link to thyroid hormone deficiency.

4. **Final Answer**: The correct answer is Cretinism.
