`p5.Color.equals` method

Increasing access

Sometimes it's useful to be able to be able to compare colors against stored colours, for example, when sampling an image with a constrained palette. It would be great if you could compare p5.Color objects with eachother, which is kind of a hassle now.

Most appropriate sub-area of p5.js?

Feature enhancement details

I suggest creating a equals() method like in string objects. I could be a piecewise comparison of either of the p5.Color.levels or p5.Color._array arrays, but I don't quite understand what their difference is in practice (which one is the master).

Start with the p5.Color API and compare the roles of the p5.Color.levels and p5.Color._array values mentioned in the issue. Decide which representation defines equality, then add equals() behavior that lets p5.Color objects be compared and verify that comparisons against stored colors work as intended.
