Image Conversion loosing colors - need help!

I'm converting a JPG image using something like: "-thumbnail 105x147! -quality 75 " + "input.jpg" + " -colorspace RGB " + "output.jpg" in my .NET code (calls convert.exe). However, upon conversion, the image losses color significantly. Upon conversion the output image gets displayed on IE. On contrary, not mentioning the "-colorspace RGB" as above, the image retains its orginal color and quality, but does not show up on IE. My initial idea (may be wrong) is that the original/input image is of CMYK color model..

convert -colorspace RGB input.jpg -thumbnail 105x147! -quality 75 output.jpg

for cmyk need to read it in as RGB, so -colorspace is before input and other options are after input

try -strip to remove profiles or add your own profiles with -profile

(just guessing here now)

Maybe the JPEG image is missing the color profile it needs!
