Expanding on what RudiC has already said...

As has been said in these forums MANY times before; the behavior of echo, when invoked with any argument containing a backslash (\) or when the first argument starts with a hyphen (-), varies from system to system and shell to shell. And, using terminal escape sequences to set text color varies from terminal (or terminal emulator) to terminal (or terminal emulator). Without knowing what the expansions of the variables in the arguments to your echo command expand to, what shell you're using, what operating system you're using, and how your environment has been initialized, it is hard to guess at what might be going wrong.

The portable way to write those escape sequences to a terminal (or terminal emulator) from a shell is to use printf instead of echo:
Code:
printf '\e[1;31m%s\t%s\t%s\t%s\t%s\e[m\n' "${var[a]}" "$time" "$end" "$day" "$score"

And, of course how your terminal or terminal emulator responds to those escape sequences can't be determined from the information you have provided. (But, on many terminals that recognize ANSI terminal escape sequences, it will produce red text).

vte

vte(1)								   User Commands							    vte(1)

NAME

       vte - virtual terminal emulator

SYNOPSIS

       vte [-2] [-A] [-a] [-B image] [-b] [-C] [-c command] [-D] [-d] [-f font] [-g] [-h] [-i] [-k] [-n] [-r] [-S] [-s] [-T] [-t terminal-type]

DESCRIPTION

       vte is simply a window wrapped around the vte embeddable terminal emulation control, which does most of the work for gnome-terminal. vte is
       used mainly to test the control. Most users do not need to use vte directly, but use gnome-terminal instead.

OPTIONS

       The following options are supported:

       -2	       Toggle double buffering. Enabled by default.

       -A	       Toggle antialiasing.  The default is that of the current GTK+ default.

       -a	       Toggle audible bell on/off. If audible bell is enabled, visible bell is disabled. If audible bell is disabled, visible bell
		       is enabled. Audible bell enabled by default.

       -B image        Use image as background.

       -b	       Toggle cursor blinking. Enabled by default.

       -C	       Open a "console" connection.

       -c command      Fork the specified command.

       -D	       Use dingus clicking: as the cursor moves over text matching a certain pattern, the matched text is highlighted and the cur-
		       sor changes shape. Disabled by default.

       -d	       Toggle update debugging. Disabled by default.

       -f font	       Specify the font to use. Default font is "Sans 12".

       -g	       Toggle whether to set geometry hints if font is changed. Enabled by default.

       -h	       Toggle highlighting.  Disabled by default.

       -i	       Toggle whether to obey attempts to set the icon name, if applications running in the terminal request this.

       -k	       Toggle whether to keep program running after GTK main loop. Disabled by default.

       -n	       Specify the number of scrollback lines. Minumum number of scrollback lines is 100. Default number of  scrollback  lines	is
		       100.

       -r	       Toggle whether to set cursor color to pale red. Disabled by default.

       -S	       Toggle launching a shell. Enabled by default.

       -s	       Toggle  whether	to  scroll  background image along with text. This option is only useful when combined with the -B option.
		       Disabled by default.

       -T	       Use transparent background. Overrides the -B option.

       -t terminal-typeSpecify the terminal type to emulate.

EXTENDED DESCRIPTION

       vte is designed to emulate the xterm program provided by the X Consortium. In turn, xterm is an almost complete emulation of the DEC  VT102
       terminal. vte supports the same extensions to VT102 as those provided by xterm, through special escape sequences.

       xterm is an evolving program. Recent changes to xterm have been been incorporated into vte.  This includes emulation of the newer DEC VT220
       escape sequences.
