Make PRs to other packages that should (and/or have been waiting to) use Color

The goal of this package is to get all Elm packages that produce colors and all Elm packages that consume colors will use this type, so this is a checklist of existing 0.19 packages that might want to switch to using Color.

Guidelines:

Make sure to understand the package author's needs and perspective rather than assuming that using the standard Color type will be the right choice for their package.
