I am having trouble converting an image as described here:
http://www.imagemagick.org/Usage/formats/#color_profile
This is the command I execute:
convert -limit thread 1 <path>/1.tif[0] -profile <profile> -quality 60 -background white -flatten -resize 146x134\> -strip jpg:<path>/1.jpg
Using one profile (sRGB Color Space Profile.icm) produces a jpg with cmyk color space and sort of inverted colors whereas using another (AppleRGB.icc downloaded from Adobe) works as expected.
Here is some info identify gathered from the source image:
Format: TIFF (Tagged Image File Format)

Resolution: 400x400

exif:PixelXDimension: 2101
exif:PixelYDimension: 2400
photoshop:ColorMode: 4
photoshop:ICCProfile: GRACol_7_340.icc

Am I missing something here or is this a bug?

Re: Wrong colorspace after conversion
Using different profiles will give different results. That is to be expected. If you get the correct results from AppleRGB.icc, then that's the one to use.
