You may like to try adding color profiles to define the colorspace in TIFF
and PNG formats.

http://www.imagemagick.org/Usage/formats/#color_profile

-colorspace is used to define how the image is stored in memory for
image processing.

-type is a low level output format type for the image,

-profile is for higher level color control of image color handling
and other special feature handling, in advanced image file formats
line JPEG, TIFF, PNG
