How can I change the color of certain aspects of widgets?

Hey everyone, I’m super new to this, I’m using the theme Travel Eye Pro so I should have access to changing all of the colors. However, when it comes to the widgets, certain parts are still the default red. The Hero Image widgets’ arrow hover is red, and the slide indicator at the bottom hovers red as well. The Book Now widget also has red accents which I cannot have. Does anyone know where I can change this? I feel like I’ve gone through all the options and found nothing.
