I managed to replicate the code and made some modifications - the end result is working.

Key changes:

added the source and referenced the AMPScript variable
removed the gtl escape OMM delimiters
added extra code to render the themeOne JSON object.

var @global_themes, @theme
set @global_themes = '{
                       "hero": {
                        "backgroundColour": "#96151D",
                        "headerColour": "#FFFFFF",
                        "copyColour": "#FFFFFF",
                        "linkColour": "#FFFFFF"
                       },
                       "themeOne": {
                        "backgroundColour": "#FFFFFF",
                        "headerColour": "#1A1A1A",
                        "copyColour": "#666666",
                        "linkColour": "#96151D"
                       }
                      }'

set @theme = "hero"
]%%
