[ISSUE]

**Title:** RGB Palette Mode Fails to Handle Opaque RGBA Colors Properly

**Description:**
When using a palette in RGB mode, providing an RGBA color tuple with an alpha value of 255 does not convert the color to RGB as expected. Instead, it attempts to allocate the color as a distinct entry, which can quickly exceed the palette limit of 256 colors and raise an error.

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

palette = ImagePalette.ImagePalette("RGB")
palette.getcolor((0, 0, 0, 255))  # Attempting to add an opaque RGBA color
```

**Expected Behavior:**
When the palette is in RGB mode and an RGBA color with an alpha value of 255 is provided, the color should be automatically converted to RGB by removing the alpha component. This allows the color to be added without exceeding the palette limit.

**Actual Behavior:**
Providing an RGBA color tuple with an alpha value of 255 in RGB palette mode results in a `ValueError`:
```
ValueError: cannot allocate more than 256 colors
```

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 Palette Mode Fails to Handle Opaque RGBA Colors Properly

**Description:**
When using a palette in RGB mode, providing an RGBA color tuple with an alpha value of 255 does not convert the color to RGB as expected. Instead, it attempts to allocate the color as a distinct entry, which can quickly exceed the palette limit of 256 colors and raise an error.

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

palette = ImagePalette.ImagePalette("RGB")
palette.getcolor((0, 0, 0, 255))  # Attempting to add an opaque RGBA color
```

**Expected Behavior:**
When the palette is in RGB mode and an RGBA color with an alpha value of 255 is provided, the color should be automatically converted to RGB by removing the alpha component. This allows the color to be added without exceeding the palette limit.

**Actual Behavior:**
Providing an RGBA color tuple with an alpha value of 255 in RGB palette mode results in a `ValueError`:
```
ValueError: cannot allocate more than 256 colors
```

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.
