This article is dedicated to learn how to change the color theme in the starter template.
So, first thing first, we are talking about the style. Right?
This means the first folder we need to access is src/styles/
All of the style related work is placed here in this folder.
Then, inside this styles/ folder, there is a file variables.less.
In this file you will find theme color variables as specified in below screenshot. And can change their values to the ones you want those to be.
So, that is all you need to change the color theme. If you are willing to make any further customization about the theme, now you know where to change :)
