Change Main Top Menu & Hover Colors & Scroll Up Arrow Change Colour

Hi. I am using RockStar theme for my website, which I love. I have 6 questions if someone could help me with please: 1. I would like to change the colour of the top menu so that the chosen page and the hover page shows a colour of #ffa100 - At the moment it is red. How do I do this? 2. I have also managed to change the home page so that it is a fixed colour of #131787, however how do I make it so that it is transparent at first glance and the main header only turns #131787 when scrolling down. 3. How do I change the colour of the other menu options which are currently white to another colour (e.g. #000000) 4. How do I change the scroll up arrow that appears when you have reached the end of the website from red to #131787 ? 5. How do I change the colour of the text at the bottom of the page from black to #131787 (This was inserted using the option of a Text Widget in Footer 1. 6. Finally how do I change the colour of the LinkedIn & Twitter Logo's from Red to #ffa100 I am using the free version, and if possible I do not want to upgrade to the pro version and wondering if there is any CSS code I can put in. At the moment I haven't amended anything (other than the normal wordpress plugins) except for the following CSS, which I have found searching through the forums here: #masthead { background-color: #131787; } .header-bg #masthead { background-color: #131787; } .entry-title { display: none; } Thanks.
