I should start by mentioning that I am looking for studies or general observations about using the color red. I am less interested in critique about the design. The specific concern that I have is if red alerts the user that they are doing something wrong or to stop. Red is typically used as an alert. So I am wondering how red impacts the user experience by perhaps causing them to hesitate.
The reason I am even using red is because it corresponds with our brand identity and I have to use red already as the color for links.
Here are my current button prototypes
So the other option I am considering is to maintain the font color and also use that for the border
Of course downloads might not really be secondary but tertiary calls-to-action which might change how we approach this.
