It is hard to tell what is wrong with your document but you do need to change your color settings - then try again
1. Change the RGB (RVB) working space to sRGB IEC1966-2.1 or Adobe RGB (1998) - if you are unsure choose the sRGB option. You do not want it set to your monitor display profile.
2. Change your color Management policies to "Preserve Embedded Profiles"
