Siteorigin Editor Title change colour

imgageoptics.co.uk

i have not understood the previous forum entries and all efforts to change the Title colour on the Home page have ended up changing the body text colour and not the colour of the title.

I can edit the Siteorigin Editor widget and on the right hand side I see

Widget Styles
Attributes
Layout Design

Under attributes I have
Widget Class
CSS Styles

All entries i have tried in the CSS Styles have changed body text and not the Title.

Can anyone advise? I want to add colour and maybe increase font size which I think is currently 1.142857143rem
