[ChoppinBlockParty]

Thank you for a great theme. Wanna give here a little feedback.

Here are the modifications that I added to my configuration.

    ;;; Improve type variable visibility (helpful in c-like language)
    '(font-lock-type-face          ((t (:foreground "#5fafaf"))))
    '(font-lock-variable-name-face ((t (:foreground "#d7875f"))))

    ;;; Improve parenthesis matching visibility
    '(show-paren-match             ((t (:background "#7f1de1" :foreground "#1f1623" :weight extra-bold))))
    ;;; Improve parenthesis matching visibility
    '(completions-annotations      ((t (:foreground "#ff6c6b"))))
    '(completions-common-part      ((t (:foreground "#4e5079"))))
    '(completions-first-difference ((t (:foreground "#da8548" :weight bold))))
