How to change the icon color of cart, search icon and add to wish list?

[akan]

I am using Magento 2. I am new to Magento and having hard time figuring this out. Any help will be greatly appreciated.  What location and code should I edit to make the changes for icon colors?

I tried to look for where to make changes but I don't know where to go and make changes.

I'd recommend inspecting the element and finding the classes assigned to these items. You should then be able to find these CSS statements in the less file for the stylesheets and update.
