bad #1 argument to 'format'

Here's the mapping I added, and it gives the error shown in image below it:

:map <M-e> <cmd>lua require'extmark-toy'.start()<CR>

Same here, 😢

Hi. Do you have a Normal highlight group defined?
I'll cater for when it's missing (I just did this for another plugin that used similar colors code). Just curious if you don't have it defined, or if it's just not defined when the color function is run.

I've pushed a fix for what I guess it is. If either of you see this, if you could - let me know if it works now.
