While I believe mutt isn't the case, you can use similar approach but
with variables only:

~/.muttrc
---
set my_colors = '2';
macro index AA ':source ~/.mutt/colors.$my_colors.muttrc<enter>'
---

~/.mutt/colors.1.muttrc
---
# colors #1
set my_colors = '2';
---

~/.mutt/colors.2.muttrc
---
# colors #2
set my_colors = '1';
---

Just tested it successfuly. Hope this helps.
