Answer

To solve the question regarding the incorrect color representation of halogens, we will analyze the colors of each halogen element step by step.

### Step-by-Step Solution:

1. **Identify the Halogens**: The halogens are found in Group 17 of the periodic table. The elements in this group include fluorine (F), chlorine (Cl), bromine (Br), and iodine (I).

2. **List the Colors of Each Halogen**:
- **Fluorine (F)**: The color of fluorine is pale yellow.
- **Chlorine (Cl)**: The color of chlorine is greenish-yellow.
- **Bromine (Br)**: The color of bromine is reddish-brown.
- **Iodine (I)**: The color of iodine is violet-black.

3. **Analyze the Given Options**:
- **Option 1**: Fluorine - Yellow (Correct)
- **Option 2**: Chlorine - Colorless (Incorrect)
- **Option 3**: Bromine - Red (Partially Correct, as it is reddish-brown)
- **Option 4**: Iodine - Violet (Correct)

4. **Determine the Incorrect Match**:
- The question asks for the color shown by halogens that is incorrectly matched.
- Chlorine is incorrectly matched as colorless when it is actually greenish-yellow.

5. **Conclusion**: The color shown by halogen that is incorrectly given is chlorine as colorless.

### Final Answer:
The incorrect color representation is **Chlorine - Colorless**.
