@rosskell To help us keep support thread separates could you please create your own thread for your question here https://colorlibsupport.com/c/activello/ instead of replying on others thread as it makes the thread messy and hard to read.
If you want to you can also add reference of this thread in your newly created thread.
We would be more than happy to help you on your new thread.
As Movin suggested, create your own topic asking how to change the default color of the body text and titles to a darker color in the Activello theme and I will write there the coding I used to make the changes.
Before making any coding changes, make sure you create an Activello child theme.
Can you please create a topic, as Movin suggested, asking how change the font style and the default color of the body text and titles in the Activello theme?
Post the link here so I’ll be notified and I will paste in the new created topic the code I’ve used, which I hope you will find helpful. Before making any changes, I advice you to create a child theme because you will make this changes in the Editor - style.css.
