Add color to 1 character in a text field for branding, Mode Theme

Hi. How do I make one character a different color in a line of text? On my homepage, in the first section, it says:

Mejor agua, más rápido.

I want to make the period at the end to be the color blue 08bde8 instead of black to make a branding statement.

Mode Theme

I figured it out on my own! I used the highlighted text portion of the customization editor.
