Hi reznickova1
I got your point, however, JA Simpli is the same as a default Joomla template, it offers some basic settings for styles only, not full settings as a Joomla template which is built with a framework like T4. That's why you don't see option for headings: H1, H2, etc....
About the blue buttons / menu item outline, the preset (orange) only covers some basic elements of site only. You can override by these custom CSS:
/*customize color when clicking menu item*/
.navbar .nav > li > a:focus {
outline: 2px solid #5e9ed6 !important;
}
/*customize button color*/
.acym_module_form .btn.btn-primary {
color: #fff !important;
text-shadow: 0 -1px 0 rgba(0, 0, 0, 0.25);
background-color: #2e93d7 !important;
background-image: -webkit-gradient(linear, left top, left bottom, from(#3498db), to(#258cd1));
background-image: linear-gradient(to bottom, #3498db, #258cd1);
background-repeat: repeat-x;
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ff3498db', endColorstr='#ff258cd1', GradientType=0);
border-color: #258cd1 #258cd1 #196090 !important;
*background-color: #258cd1;
filter: progid:DXImageTransform.Microsoft.gradient(enabled = false);
}
and change to your desired color
