White (#FFFFFF) becomes yellowish (#FCFEFC) while resizing GIF

[raidoa]

Hi,

Just discovered a challenge where uploaded GIF files will be turned bit yellow after resizing.
JPG and PNG are fine.

Will it go under bug or is something missing from the code?

Using version 2.4 with rather plain code:

use Intervention\Image\ImageManagerStatic as Image;

$inputFile = "input.gif";
$img = Image::make($inputFile)->widen(1024, function ($constraint) {
    $constraint->upsize();
  }
);
$img->save("output.gif");

output.gif:

input.gif:

I realize this issue was created over 2 years ago now, but I am seeing the same issue with GIFs in version 2.5. This is the single mention of the issue that I've been able to find anywhere on the interwebs. I'd be grateful if anyone had any suggestions on a fix or workaround.

use Imagick;
$im = new Imagick($image);
$im->resizeImage(500,582,(FIlter),1,false);
that filter para causing the issues,if I resize without (filter),param (No change in color in output image).
Resize Using Imagick Solves,But I dnt know how to edit resize method in Intervention.
