MacBook keyboard backlight options

I was setting up my new MacBook screen with a red filter so I can use it at night while making astronomical observations.

Can the backlight on the keyboard also be changed to red? Red helps the eyes adjust from screen to sky or screen to telescope faster.

If you reply, please be nice. The last person who asked this question wasn't taken terribly serious and was slammed with some presumptively rude comments and accusations. This has nothing to do with vanity or decoration or art.

Thank you.
