Best API for setting pen color?

See original GitHub issue

Right now pen color can be set to any valid CSS color string (like red, #f00, rgb(255, 0, 0), or others).

This isn’t great because it doesn’t leave much wiggle room for setting color, saturation, brightness, or transparency independently (which is possible in Scratch).

What’s the best API for dealing with colors? Color strings are handy, but underpowered.

@PullJosh == works for comparing them if you implement the toString function to return a color string (e.g. hex) — it’d be comparing those instead of the actual objects (which is what === usually does).

Add a Color type? This is somewhat similar to a special Pen class, but unspecialised.

this.penColor = Color.rgb(1.0, 0.0, 0.0)
console.log(this.penColor == Color.RED) // true
console.log(this.penColor == Color.rgba(1.0, 0.0, 0.0, 1.0)) // true
console.log(this.penColor == Color.hsv(0.0, 1.0, 0.5)) // true (I think)

this.penColor.b += 0.5

I personally like RGB(A) much more than HSV(A), so providing the option would be nice 😃
