Fix: Resolve parameter reassignment issue in Color.divideLocal

- Updated the `divideLocal` method to avoid reassignment of the input
parameter `a`.
- Ensured proper functionality by using the `this` keyword for color
components (r, g, b, a).
- Addressed potential confusion and bugs caused by parameter shadowing.

Thanks and shout-out to my nerd coding buddy and long-time friend tim
for pointing this out—you're a lifesaver!
