Theme colors; scallop banner

Hi!

I am having problems changing the theme colors and also problems getting the white banner at the top to be scalloped / wavy as shown in the demo page, instead of a straight white box.

Colors:
1. I want the search bar magnifying glass icon search icon to be purple not pink, but I can’t find where to change the setting for it.

2. As soon as I start scrolling down the home page, the purple background behind my logo turns pink, and I can’t find where to change that pink, please help.

Banner:
3. On some of my pages, such as https://toptierconfections.com/about/ you can see the white scallop banner design at the top; however on my home page toptierconfections.com, there is no banner. How can I fix this? The home page is designated as “Front Page” in the list of pages on my admin site. The template for the page is designated as “Ibtana block” because when I designate it as “home page,” it goes INSANE with 3 logos stacked and the block format completely destroyed.

Thank you for the assistance,

Heather
