Experimenting with After Effects

As I began making advertsimenst boards to go alongside the products, I wanted to experiment with animating them as I intended to have a social media aspect to it to it, However I ran into trouble animating. When rendering the colours didnt come out true to the design and after trying many tactics to reslove this, the best I could get was the original colour but only at full opacity. so I decided not to use as final outcome as I would not be consistent witht the campaign. I also tried to create a squiggly pattern to resemble that of a susage for social media but ran into the same trouble with the rendering of the colours as you can see in figurees 1 and 2 the colours are very dark.
