Question:
I was wondering of a way to dynamically change which class you are calling. ie:
'<%= "text-#{color} bg-#{color}" %>' << this code is not recommended since tailwind needs the full class name to build.

Answer(chris):
you can supply a custom color to Tailwind in the config
module.exports = {
colors: {
'primary': 'var(--primary-color)',
same thing as a regular color there

Very informative, thank you Chris and Willard!
