Are there any best practices for resizing images in PHP to avoid color distortion?

Resizing images in PHP can sometimes result in color distortion due to the way the resizing algorithm interpolates pixel values. To avoid this, it's best to use a high-quality image processing library like Imagick or GD, and to ensure that the library is set to use a high-quality interpolation method such as Lanczos. This will help preserve the original colors and details of the image during the resizing process. 

// Example code using Imagick to resize an image without color distortion
$image = new Imagick('input.jpg');
$image->resizeImage(800, 600, Imagick::FILTER_LANCZOS, 1);
$image->writeImage('output.jpg');
$image->destroy();
