This is all changeable, but you really need to create a child theme to put these changes in or they’ll be lost on a theme upgrade.
If you’re not familiar watch this video first

In your case the “template” on line 5 of your child theme will be “appointway” and suggest you call your directory and theme “appointwaychild”
Then where he adds code, you’ll be looking to add
For the header color
.header_container {
background: none repeat scroll 0 0 #467D08;
}
You’ll need to change the #467D08 to whatever colour you need.
If you don’t know an easy way to find out the number you need for your colour – download colorcop to your PC – this will let you chose the right color, and then show you the code for it

Then for the background color add
body {
background: none repeat scroll 0 0 #CC9966 !important;
}
and change #CC9966 to the colour you want
Then your first heading text color is
.page_info h1 {
color: #010101;
font-size: 28px;
line-height: 35px;
margin-bottom: 20px;
text-align: center;
}
so to change this to white alter to #ffffff
Finally your second header is
.page_info h3 {
color: #5C5C5C;
font-size: 20px;
margin-bottom: 0;
text-align: center;
}
Again if you want this text white change #5C5C5C to #ffffff
You’ll probably need to play a bit to get all that to work – I’ve just skimmed some code across and not tested it
Have fun
