Negative Look Ahead. Exclude Expression-CodePudding

I want to exclude the following: Anything starting with a curly brace, followed by the word color. After color there can be anything. Once I see the closing curly brace, that entire chunk needs to be eliminated. See below for the bolded stuff for an example. This is my expression so far.

^(?!.*({color})).*

What am I doing wrong? Thank you.

('|Activity|Planned Dates|Actual Dates|Status|\r\n'
'|Dev Cut Off|06/03/22\xa0|06/03/22|Complete|\r\n'
'|AOS Integration|06/10/22|06/10/22|Complete|\r\n'
'|**{color:#de350b}**QA Deploy{color}|{color:#de350b}06/14/22\xa0'
'{color}|{color:#de350b}06/16/22{color}|\r\n'
)

So use

text = re.sub(r'\{color[^{}]*}', '', text)

See regex proof.
