Problem description
Several color schemes specify colors beyond the 16 color palette. I've noticed this has been the case for many months but never reported it.

Steps to reproduce

1. Select an afflicted color scheme.
2. Display colors 16 through 21 of the 256 color palette.

Expected behavior
Colors 16 through 255 should be the same no matter which color scheme is in use.

Additional information
After extracting Termux: Styling's APK, running this grep command inside of assets/colors will show the list of files affected:

grep -Pl '^color(1[6-9]|[2-9][0-9]+)=' ./*.properties

This will show some of the colors that should be consistent no matter which color scheme is selected:

printf '\033[38;5;255m'
for i in `seq 16 21` ; do
    printf "\033[48;5;${i}m.${i}."
done
printf '\033[m\n'
