We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
[ISSUE]
**Title:** RGB ImagePalette Does Not Reject Non-Opaque RGBA Colors

**Description:**
When using an `RGB` mode `ImagePalette`, passing a color with an alpha value less than 255 (translucent color) does not raise an error as expected. This can lead to unexpected behavior when handling image palettes that should strictly contain opaque colors.

**Example Buggy Code:**
```python
from PIL import ImagePalette

# Create an RGB palette
palette = ImagePalette.ImagePalette(mode="RGB")

# Attempt to add a translucent color
palette.getcolor((0, 0, 0, 128))
```

**Expected Behavior:**
Passing a translucent RGBA color to an `RGB` mode `ImagePalette` should raise a `ValueError` indicating that non-opaque colors are not supported.

**Actual Behavior:**
No error is raised when a translucent RGBA color is added to the `RGB` palette, allowing potentially invalid palette data to be processed.

Please first localize the bug based on the issue statement, and then generate *SEARCH/REPLACE* edits to fix the issue.

Every *SEARCH/REPLACE* edit must use this format:
1. The file path
2. The start of search block: <<<<<<< SEARCH
3. A contiguous chunk of lines to search for in the existing source code
4. The dividing line: =======
5. The lines to replace into the source code
6. The end of the replace block: >>>>>>> REPLACE

Here is an example:

```python
### mathweb/flask/app.py
<<<<<<< SEARCH
from flask import Flask
=======
import math
from flask import Flask
>>>>>>> REPLACE
```
</solution>

Please note that the *SEARCH/REPLACE* edit REQUIRES PROPER INDENTATION. If you would like to add the line '        print(x)', you must fully write that out, with all those spaces before the code!
Wrap each *SEARCH/REPLACE* edit in a code block as shown in the example above. If you have multiple *SEARCH/REPLACE* edits, use a separate code block for each one.
[ISSUE]
**Title:** RGB ImagePalette Does Not Reject Non-Opaque RGBA Colors

**Description:**
When using an `RGB` mode `ImagePalette`, passing a color with an alpha value less than 255 (translucent color) does not raise an error as expected. This can lead to unexpected behavior when handling image palettes that should strictly contain opaque colors.

**Example Buggy Code:**
```python
from PIL import ImagePalette

# Create an RGB palette
palette = ImagePalette.ImagePalette(mode="RGB")

# Attempt to add a translucent color
palette.getcolor((0, 0, 0, 128))
```

**Expected Behavior:**
Passing a translucent RGBA color to an `RGB` mode `ImagePalette` should raise a `ValueError` indicating that non-opaque colors are not supported.

**Actual Behavior:**
No error is raised when a translucent RGBA color is added to the `RGB` palette, allowing potentially invalid palette data to be processed.

--- BEGIN ISSUE ---
[ISSUE]
**Title:** RGB ImagePalette Does Not Reject Non-Opaque RGBA Colors

**Description:**
When using an `RGB` mode `ImagePalette`, passing a color with an alpha value less than 255 (translucent color) does not raise an error as expected. This can lead to unexpected behavior when handling image palettes that should strictly contain opaque colors.

**Example Buggy Code:**
```python
from PIL import ImagePalette

# Create an RGB palette
palette = ImagePalette.ImagePalette(mode="RGB")

# Attempt to add a translucent color
palette.getcolor((0, 0, 0, 128))
```

**Expected Behavior:**
Passing a translucent RGBA color to an `RGB` mode `ImagePalette` should raise a `ValueError` indicating that non-opaque colors are not supported.

**Actual Behavior:**
No error is raised when a translucent RGBA color is added to the `RGB` palette, allowing potentially invalid palette data to be processed.

Please first localize the bug based on the issue statement, and then generate *SEARCH/REPLACE* edits to fix the issue.

Every *SEARCH/REPLACE* edit must use this format:
1. The file path
2. The start of search block: <<<<<<< SEARCH
3. A contiguous chunk of lines to search for in the existing source code
4. The dividing line: =======
5. The lines to replace into the source code
6. The end of the replace block: >>>>>>> REPLACE

Here is an example:

```python
### mathweb/flask/app.py
<<<<<<< SEARCH
from flask import Flask
=======
import math
from flask import Flask
>>>>>>> REPLACE
```
</solution>

Please note that the *SEARCH/REPLACE* edit REQUIRES PROPER INDENTATION. If you would like to add the line '        print(x)', you must fully write that out, with all those spaces before the code!
Wrap each *SEARCH/REPLACE* edit in a code block as shown in the example above. If you have multiple *SEARCH/REPLACE* edits, use a separate code block for each one.
