This animation is designed for Hydralyte. I use Adobe After Effects to design that.

The main concept of Hydralyte brand is to give your body more water to prevent dehydration.  So I pick up Fluid theme for this design. As you can see from the image below, I treat logo as Alpha layer and put fluid water footage at the backend. So it will look like water fill into the logo.

In terms of colour, client wants to follow their style guide and use orange colour.
