A macro to highlight Nat 19s with a blue box 😀

A neat little trick for those playing on Roll20 who like to use macros for monster attack rolls. The following macro will highlight rolls as follows:

Nat 19s with a blue box

Nat 20s with a green box

Nat 1s with a red box

Hope this helps, and many thanks for Dianna over on the Roll20 forums for her genius!
