How can using ImageCreateTrueColor instead of ImageCreate potentially solve the issue?

Issue: The issue may be related to the color palette used by the image created with ImageCreate, which can cause color distortion or unexpected results. Using ImageCreateTrueColor instead of ImageCreate can solve this problem by creating a true color image with a full range of colors. Code snippet:

// Create a true color image with ImageCreateTrueColor
$image = ImageCreateTrueColor($width, $height);

// Use the image resource to manipulate or display the image
// Example: imagefilledrectangle($image, 0, 0, $width, $height, $color);

// Output the image to the browser or save it to a file
// Example: imagepng($image, 'output.png');

// Free up memory by destroying the image resource
imagedestroy($image);
