What potential issues or pitfalls should be aware of when handling color modes in image processing with PHP?

Issue: One potential pitfall when handling color modes in image processing with PHP is converting between different color modes incorrectly, leading to distorted or incorrect colors in the final image. To avoid this issue, always ensure that you are using the correct color mode conversion functions provided by PHP's GD library. 

// Example of converting an image to grayscale using the correct color mode conversion function
$image = imagecreatefromjpeg('input.jpg');
imagefilter($image, IMG_FILTER_GRAYSCALE);
imagejpeg($image, 'output.jpg');
imagedestroy($image);
