I tried attaching my photo but keep getting an error.

Thanks

You get a color shift because a color saturates before the others. You can convert the image to B&W using Colors ➤ Desaturate. Changing the image mode to grayscale is another way but it has implications...

Colors > Desaturate did the trick. Thanks
