chore: Update `colorSpace.darken` utility for interaction states

[josh-bagwell]

🚀 Feature Proposal

The colorSpace.darken utility will need to be updated for interactive states (i.e. hover and active).

Motivation

To simplify the util and add semantics.

Example

// This is the original util and will stay put as it gives the most options
colorSpace.darken()
// These two will be simpler to use with one argument for a color
colorSpace.hover()
colorSpace.pressed()
