How to change the orange and green button on home page?

See screenshot for the buttons I am talking about...

 

Hello,

Greetings from InkThemes!

It seems that you want to change the color of that buttons.

So, to change the color of header button, you just need to paste the code given below in Custom CSS section (Appearance -> Theme Options -> Styling Options -> Custom CSS) of your dashboard.

Code:

.header .post_add_btn .btn_center, .header .post_add_btn .btn_left, .header .post_add_btn .btn_right{
    background: red !important;
}

For next button, code is given below,

Code:

.search_wrapper .search_item.third .search_submit {
    background: lightslategrey !important;
}

NOTE: Change color as per your interest.

Hope it will resolve your issue

Do let me know if you need more assistance,

Thanks & Regards!
