1: Why are all the dashes ('-') backslashed?
2: You do not need the trailing '.*' on all these patterns.
| color body brightmagentadefault ^\\+\-\-\-\\[ STDIN \\]\-\-.*
| color body brightmagentadefault ^\-\-\-\-\\[ manpage \'.*\'
\\]\-\-.*
The inner '.*' here may be raising the cost to evaluate this pattern.
See if [^\]*] works better than .*.
| color body brightmagentadefault ^\\+\-\-\-\\[ manpage \'.*\'
\\]\-\-.*
| color body brightmagentadefault ^\-\-\-\-\\[ command \'.*\'
\\]\-\-.*
| color body brightmagentadefault ^\\+\-\-\-\\[ command \'.*\'
\\]\-\-.*
| color body brightmagentadefault '^| '
You probably want to backslash the '|' here - it is a regexp punctuation
character.

I can't speculate about the memory usage.
But it is easy to write regular expressions that are very expensive.
I would do the following:
1: Get rid of the backslashes on the '-' characters.
The just make everything hard to read.
Test that the patterns still work.
2: Get rid of the trailing '.*' on each pattern.
It is not needed and just makes extra work.
(Urr, unless mutt colours only the matched part of the line.
I have not checked that. But it is still a useful experiment.)
Test that the patterns still work.
And if so, see if the performance issues are improved.
3: Comment out the patterns with '.*' in the middle.
See if the performance problems are affected.
I would expect that you could comment out all the patterns
in your snippet and add them back one at a time.
This should tell you that a particular pattern is expensive,
and presumably the others like it.
What results do you get?
