Can I use variables when initializing a mixin?

Question

Pug

I load SVG with this mixin: +use('search', '32', '32', '#4990e2', '')
But writing the same colors in each is not comme il faut, so it would be more convenient to store them in a file, include and load through variables, but this method will not work:
- var jColor = '4990e2'
+use('search', '32', '32', '#{jColor }', '')
it will not work if you make an escape !, change quotes, put spaces. How to be? Reconcile?

Answer 1

Why is it so tricky, it doesn't work like this?
+use('search', '32', '32', '#' + jColor, '')
