Site title styles not using custom font

Good afternoon everyone,

I am having trouble with my custom font.

I have changed the styles of all headers in the custom css, however the site title will not change from the previous adobe font selected. I have tried going into 'assign styles' and changing the settings from 'custom' to 'heading', but it won't change like the rest of it. 

I'd rather keep it all in the custom font, rather than upload a logo, so that the title changes colour with the pages too. Does anyone know how to resolve this issue? Any help would be much appreciated.

I see you solved by using a Logo image?
