Change Slider "join now" button color

Ok, so I've read through the help forum for a previous solution. None have worked for me yet. What I want to do is change the "Subscribe" button face (and text) color. Here is my Custom CSS style code as of now:

.header .logo {
text-align: center;
}

.page-template-template-contact-php .content-bar div {
display: none;
}

#slider_wrapper .entry .entry_btn:hover, #respond input#submit
{
background: green !important;
}
#slider_wrapper .entry .entry_btn:hover, #respond input#submit:hover
{
background: green !important;
}

#menu li.current_page_item a, #menu li.current-menu-item a, #menu li.current-menu-parent a, #menu li.current_page_parent a, #menu li a.selected, #menu li a:hover, #menu .ddsmoothmenu li li:hover a, #menu .ddsmoothmenu li li:hover
{
background:green !important;
}

The last part was from a previous request who wanted to change menu button AND slider button color. I like the menu button color (green) so I'll leave it. What part do I change, though, to turn the "Subscribe" button color green? The theme color is set to gray (which I like). I just want to make the button not-gray.

thanks for your help,

Actually, I realized the old CSS code was from a previous theme (I just changed over to Subscribely). So I deleted it all. Lets start from scratch!

 

Actually, I found it. If you right-click on the button face and select "Inspect Element", the code that sets all that opens up in a side panel. So I just selected the button face color and added the following to the Custom CSS code section:

#slider_wrapper .entry .entry_btn, #respond input#submit {
background: green;
}

Easy fix. Hope this helps someone else searching for the same.
