Call to Action Typography

With the word 'thirsty' I wanted to make the font plain and stark black to emphasize the bareness of the scene. I also made the font thin to give a feeling of dehydration and starvation. I also manipulated the dot on the question mark to form a water drop to highlight the lack of water in the scene. 

I left the word 'conserve' blue with a thicker typography in order to emphasize the health and hydration that water provides. The thick blue also gives an idea of the abundance of water if we simply follow the simple command to 'conserve.' The simplicity of the font highlights that the word is a command, and gives the reader the idea that the command is a simple task to follow.
