How to implement 256 colors output in TTY on Debian Jessie?

Question

linux

Hello gentlemen. The PC has a freshly installed Debian Jessie. When I connect to the PC via SSH using PuTTY\ConnectBot, I see 256 colors in the console (xterm-256color) - everything is fine with that. But when I'm directly behind the PC monitor, I don't see 256 colors in the TTY console. I would like to see 256 colors not only in PuTTY\ConnectBot, but also on the monitor screen in the TTY console. Tell a newbie: is it possible in any way to implement this? If so, how?
PS The Intel GMA 3650 video card is built into the Intel Atom N2800 stone. The blacklist gma500_gfx line was added to the /etc/modprobe.d/fbdev-blacklist.conf file immediately after the system was installed. Immediately after installing the system, the /etc/default/grub file was brought to the following form:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vga=0x0318 rootflags=data=writeback"
GRUB_CMDLINE_LINUX="quiet splash vga=0x0318 rootflags=data=writeback"

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=1024x768-24

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

Sincerely.
