change color of the stock availability text on all product pages

Please can you advise any CSS ,The stock availabilty text(in stock,quantity,can be back ordered etc) on my site seems to have defaulted(it was fine but it seems to me they have changed it on a update) to woocommerce colour choice ,which is very feint,how can i change this to show a bolder colour?
Is it possible to define a different colour for each notice i.e stock,quantity,can be back ordered,out of stock?
I am using DIvi theme and have no plug ins or CSS that will add conflict to this issue.
Many thanks

 

Thanks for your prompt reply,example URL https://www.electricbray.com/product/ensto-enclosure-spck182515g/

This is a single product page and will need to also apply to variation product pages.
