How do i change the button hover colour in DAWN theme?

How do i change the hover button colour on my website?

Underneath my portfolio (blog) there is a button that says “view portfolio”. When i hover over i cannot read the writing. How do i change this colour please?

My URL is: https://www.sandraleedesigns.com/

@sandraleedesign ,

a:hover {
    color: #4e4e4e;
}

Add this css at the bottom of Online Store->Theme->Edit code->Assets->base.scss.liquid

Thank you so much! It worked! But is there a way to make it use a colour that i select from the settings within the theme customizer?

@sandraleedesign ,

check the color code there and change it in the css instead of #4e4e4e
