interpolation of values to hue not working as espected

[ericvida]

Description

I expected the ability to pass a dynamic value to a hue style property, but it does not work as expected.
Here's a code to reproduce the issue, and I attached a Scrimba link.

tag App
	colors = ["rose", "amber", "violet"]
	<self>
		css span px:1em
		<.color-interpolation> # ✅ working
			for item in colors
				<span[bg:{item+3}]> item
		<.hue-interpolation> # ❌ not working
			for item in colors
				<span[hue:{item} bg:hue3]> item

imba.mount <App>

This feature would be useful for switching themes with user input.
Maybe using custom modifiers the preferred method.
