S7 pre-installed Calendar - Change date number color

[AC Question]

In "month view," current date number is turquoise; all others are black. Is there a way to change only the current date number from turquoise to red (to make it stand out a little better?)

When I look at month view on the stock calendar, my numbers are black. I'm wondering if the color of the numbers correlate to the theme or launcher you are using. I don't use the stock calendar; I'm using the Google calendar and a baseball theme, and all my numbers are black.
