Do you have a link to your site with an example of a section that you want to change? Once I take a look, I can tell you exactly where you’ll need to add your color code.
In the future, as mentioned here in the Forum Rules – https://appfinite.com/topic/forum-rules/ it’s recommended to create separate forum topics/threads for each question you have so the forum will be more organized and easier to search for the topics you need. I’m only mentioning it since this is your first time here. So definitely read through those so you can become familiar with how the forum works.
Your English looks fine to me 🙂
