I have just started to work with Magento 2 and I have the building blocks in place for my custom theme.
I'm only restyling the default luma theme and overriding the styling to fit in more with our business.
I am wondering how I can add more colors to _colors.less, Is it a simple case of adding more definitions to the file in the below location?
lib\web\css\source\lib\variables
or do I override this somehow? I can't find much documentation on adding your own custom colors, just guides that use the default colours provided by Magento.
