I managed to customize themes after they load with:
(custom-set-faces
`(font-lock-keyword-face ((t :weight bold)))
`(hl-line ((t (:background ,(doom-color 'base5)))))
)
Thing is I want to change hl-line color only for one selected theme version - 'doom-material'. How do I hook to theme-change / type = 'doom-material' event in my config?
