Termux fades to white even though background is black.

[ScottFreeCode]

When using Beacon 1.3.4 or 20190104.1931 on Android under Termux (Emacs 26.3), with the default coloring (no Emacs theme, no terminal customization), the background is black but the beacon line fades to white. This issue is not present in other terminals I've tried. If it would help narrow down the issue I can experiment with coloring Emacs and see if this persists.

Cool package, by the way! Great example of how Emacs can be customized in ways most editors never could be.
