+vtcol can be used in /etc/rc.d/rc.local to set the colour scheme at boot:
+
+vtcol --scheme solarized_light
+
+It is also possible to add it to your initrd to have the colour scheme set early in the boot process.
+
+Example:
+
+kernel=4.4.38
+mkinitrd -c -k "$kernel" -f ext4 -r /dev/disk/by-uuid/<some uuid> -m ext4:<more modules> -u -o /boot/initrd-"$kernel".gz -s 
+/tmp/initrd-tree-"$kernel"
+install -m 755 /usr/bin/vtcol "/tmp/initrd-tree-$kernel/bin/vtcol"
+sed -i '159i \/bin\/vtcol --scheme solarized_dark' /tmp/initrd-tree-"$kernel"/init
+mkinitrd -k "$kernel" -f ext4 -r /dev/disk/by-uuid/<some uuid> -u -o /boot/initrd-"$kernel".gz -s /tmp/initrd-tree-"$kernel"

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
