After effect mp4 vid hue and lightness shift

So does anyone know what can be done to fix this. My colour always change when I export to mp4, it looks good in avi tho. I've compared the colours in photoshop and found out the exported .mp4 version can be made the same as original by changing hue to -5 and lightness -4. I tried to add a colour correction in AE and it kinda worked but that isnt practical. Does any one know how to get better colour fidelity when exporting to mp4.

Thanks
