Aperture 3 import color issues

Sorry if this has been covered……please point me to the correct posts. Aperture imports a tif Adobe98 file and hoses the colors. Example: a fill of (72, 182, 70) in an A98 file imports into AP3 with a major color change. If I take that same file and convert it in PS to sRGB then import that to AP3 the colors basically are the same as the non imported A98 file in PS. Some think things changed when AP3 came out and others think it is a Lion issue. I think Colorsync is the color engine for Aperture… How can color issues happen in an Apple product? Thanks for all helpful suggestions. DAvid
