Emphasizing "X days left in trial"

Question

My product shows an indication for number of days left in the free trial:

When the number of days left is 3 or less, I would like to emphasize it by coloring in red. What would be the correct way?

1. Coloring just the number of days:

   

2. Coloring "X days":

   

3. Coloring the entire sentence:

   

Answer 1

Second option seems most appealing to me as it's visible enough but not too much.

Have you considered showing a reverse progress bar visually displaying the countdown? Like this

Answer 2

Personally I would, first of all drop the contact sales button and make the text clickable linking to where to buy the full version. As according to me having a button visible throughout the trial period tends to add visual weight. As for the color I think coloring the whole text would be better.
