Changing my button color on hover

Hi! I really want to update the color of my buttons to change when hovered upon ( black "email me" and arrow button turn to blue when hovered on) I found this code 

.small-button-shape-pill .sqs-block-button .sqs-block-button-element--small:hover {
 background-color: #000000 !important;
 color: #0000ff !important
}

and tried to use it but with my site colors and its not working, also if someone can help me change the nav bar page im currently on to be blue, Id appreciate it!! 🙂
