Color blindness testing is common in many medical examinations, with each person and image presenting unique challenges. Some images can be particularly difficult to discern, potentially leading to misdiagnoses of color deficiency or color blindness if not identified accurately and promptly. To address these issues, the Color Blindness Self-Test app includes various color blindness test images and convenient features to aid in learning and improve examination outcomes.

The app offers several useful functionalities:

1. Test Mode: Randomly selects images from a question bank for color discrimination testing, providing detailed answer analysis for comparative results.

2. Practice Mode: Allows focused viewing of specific images in a question-and-answer format, automatically adding incorrectly answered questions to a review section for targeted learning.

3. Image Viewing Mode: Sequentially displays images and answers, with the option to use color blindness filters to reveal the true content of the images.

4. Review Section: Automatically compiles incorrectly answered questions for personalized study and improvement.

5. Bookmarking: Enables users to save preferred images for easy access and further study.

6. Custom Image Creation: Edit and create personalized image sets for tailored testing and learning experiences, conveniently accessible on mobile devices.
