We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
[ISSUE]
**Title:** `getcolor` Does Not Correctly Handle RGB Inputs in RGBA Palette Mode

**Description:**
When using the `ImagePalette` with the "RGBA" mode, providing an RGB tuple to the `getcolor` method does not automatically append an alpha value of 255. This leads to discrepancies where the same color is treated differently based on the presence of the alpha channel.

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

# Initialize palette in RGBA mode
rgba_palette = ImagePalette.ImagePalette("RGBA")

# Retrieve color with RGB input
color_rgb = rgba_palette.getcolor((0, 0, 0))

# Retrieve color with RGBA input
color_rgba = rgba_palette.getcolor((0, 0, 0, 255))

print(color_rgb, color_rgba)  # Expected both to be the same
```

**Expected Behavior:**
When the palette mode is set to "RGBA", providing an RGB tuple like `(0, 0, 0)` to `getcolor` should internally convert it to `(0, 0, 0, 255)`. Therefore, both `color_rgb` and `color_rgba` should return the same value, ensuring consistency in color handling.

**Actual Behavior:**
The `color_rgb` and `color_rgba` values differ because the RGB input does not automatically receive the alpha channel, causing the test to fail:
```
0 != 1
```
This inconsistency can lead to unexpected behavior in applications relying on accurate color representation.

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.

**Title:** `getcolor` Does Not Correctly Handle RGB Inputs in RGBA Palette Mode

**Description:**
When using the `ImagePalette` with the "RGBA" mode, providing an RGB tuple to the `getcolor` method does not automatically append an alpha value of 255. This leads to discrepancies where the same color is treated differently based on the presence of the alpha channel.

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

# Initialize palette in RGBA mode
rgba_palette = ImagePalette.ImagePalette("RGBA")

# Retrieve color with RGB input
color_rgb = rgba_palette.getcolor((0, 0, 0))

# Retrieve color with RGBA input
color_rgba = rgba_palette.getcolor((0, 0, 0, 255))

print(color_rgb, color_rgba)  # Expected both to be the same
```

**Expected Behavior:**
When the palette mode is set to "RGBA", providing an RGB tuple like `(0, 0, 0)` to `getcolor` should internally convert it to `(0, 0, 0, 255)`. Therefore, both `color_rgb` and `color_rgba` should return the same value, ensuring consistency in color handling.

**Actual Behavior:**
The `color_rgb` and `color_rgba` values differ because the RGB input does not automatically receive the alpha channel, causing the test to fail:
```
0 != 1
```
This inconsistency can lead to unexpected behavior in applications relying on accurate color representation.

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.
