Expected behavior*change a primary button color*Actual behavior*not changing*Resources (screenshots, code snippets etc.)

Hi, I'm new to css and html.

I wanted to override a color of 'primary' and found your document about color theme.

It says using _variable.scss in src/scss/free folder

So, I just change the color of $primary and save it. However, nothing has changed.

I googled a lot. but only Bootstrap one can be founded and that way seems to be little different.

I'm sorry, but could you explain ,step by step, what I should do to customize primary color?

It will be great, if this is on docmentation as well.

Thanks!
