Answer

To answer the question about the color of night-blooming flowers, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Night-Blooming Flowers**: Night-blooming flowers are those that open and release their fragrance during the night. This is often an adaptation to attract nocturnal pollinators.

2. **Pollination Mechanism**: Most night-blooming flowers do not rely on daytime pollinators like bees, which are attracted to bright colors. Instead, they may be pollinated by moths or other nocturnal insects.

3. **Color Adaptation**: Since these flowers bloom at night, they do not need to attract daytime pollinators. Therefore, they typically do not invest energy in producing vibrant colors.

4. **Common Color of Night-Blooming Flowers**: The most common color for night-blooming flowers is white or whitish. This is because white flowers are more visible in low light conditions, which helps nocturnal pollinators locate them.

5. **Eliminating Other Options**:
- **Violet to Purple**: These colors are more suited for daytime pollination.
- **Red**: This color is also primarily attractive to daytime pollinators.
- **Yellow**: Similar to red, yellow flowers attract daytime insects.

6. **Conclusion**: Based on the above reasoning, the correct answer to the question is that the color of night-blooming flowers is usually **whitish**.

### Final Answer:
The color of night-blooming flowers is usually **whitish**.
