Remove theme’s reddish-pink button color from The Events Calendar Pro elements?

Hello, I'm using AudioMan free theme in conjunction with The Events Calendar Pro (recently installed). The Events Calendar Pro is inheriting the reddish-pink button color from the theme on several button and dropdown elements. See https://www.stevejohnsonmusic.com/events/ and notice the Date Range dropdown, the Find Events Button, the View dropdown (List, Month, etc) at the top, and the Subscribe To Calendar dropdown at the bottom. There are a couple other instances where the red color is incorrectly displaying. If I do a live preview with a different theme, the problem no longer exists, so this appear to be specific to the AudioMan theme. Is there a way to remove the theme's color from the calendar elements? Thanks, Steve
