A collection of established color values using color.NRGBA (non-alpha-premultiplied).

import "gio.tools/colors"

// Material colors such as...
colors.Pink200

colors.BlueGrey500

// Apple foundation colors such as...
colors.IOSDarkBlue
colors.MacOSLightPurple

Why not alpha-premultiplied (color.RGBA)?

1. Gio APIs use color.NRGBA, and the primary intent of this package is for use with Gio.
2. As mentioned in the commit description when Gio switched, most APIs use non-premultiplied for the sake of clarity.
