Give some examples of the ions which are coloured but diamagnetic in nature.

Explanation

To answer the question regarding examples of colored ions that are diamagnetic in nature, we can follow these steps:

### Step 1: Understand the Terms
- **Colored Ions**: Ions that absorb certain wavelengths of light and reflect others, giving them color.
- **Diamagnetic**: A property of a substance that has all its electrons paired, resulting in no net magnetic moment.

### Step 2: Identify Relevant Ions
We need to identify ions that are colored but have all paired electrons, making them diamagnetic.
