Assign user input to already declared array
What I am doing is creating a top menu, which a user will select a choice with a number entry. That number corresponds to a string in an array. I then want to assign that response to another array I've already declared.

For example:
Code:
#!/bin/bash
colors=(red blue yellow)
red=(cherry fire)
blue=(baby sky)
yellow=(canary banana)

echo "Choose a color: 0) Red, 1) blue, 2) Yellow"
read choice

************
From there, the user will enter 1, 2 or 3. How do I then assign the value of say colors[2] to my array $yellow that I have already declared?

I'm sure this is easy, but I cannot figure this out. And yes, I'm new to scripting.

secolor.conf

secolor.conf(5) 						File Formats Manual						   secolor.conf(5)

NAME

       secolor.conf - The SELinux color configuration file.

DESCRIPTION

       This  optional  file controls the color to be associated to the context components associated to the raw context passed by selinux_raw_con-
       text_to_color(3), when context related information is to be displayed in color by an SELinux-aware application.

       selinux_raw_context_to_color(3) obtains this color information from the	active	policy	secolor.conf  file  as	returned  by  selinux_col-
       ors_path(3).

FILE FORMAT

       The file format is as follows:
	      color color_name = #color_mask
	      [...]

	      context_component string = fg_color_name bg_color_name
	      [...]

       Where:
       color
	      The color keyword. Each color entry is on a new line.
       color_name
	      A single word name for the color (e.g. red).
       color_mask
	      A color mask starting with a hash (#) that describes the hexadecimal RGB colors with black being #000000 and white being #ffffff.
       context_component
	      The context component name that must be one of the following:
		     user, role, type or range
	      Each context_component string ...  entry is on a new line.
       string
	      This is the context_component string that will be matched with the raw context component passed by selinux_raw_context_to_color(3).
	      A wildcard '*' may be used to match any undefined string for the user, role and type context_component entries only.

       fg_color_name
	      The color_name string that will be used as the foreground color.	A color_mask may also be used.
       bg_color_name
	      The color_name string that will be used as the background color.	A color_mask may also be used.

EXAMPLES

       Example 1 entries are:
	      color black  = #000000
	      color green  = #008000
	      color yellow = #ffff00
	      color blue   = #0000ff
	      color white  = #ffffff
	      color red    = #ff0000
	      color orange = #ffa500
	      color tan    = #D2B48C

	      user * = black white
	      role * = white black
	      type * = tan orange
	      range s0-s0:c0.c1023 = black green
	      range s1-s1:c0.c1023 = white green
	      range s3-s3:c0.c1023 = black tan
	      range s5-s5:c0.c1023 = white blue
	      range s7-s7:c0.c1023 = black red
	      range s9-s9:c0.c1023 = black orange
	      range s15:c0.c1023   = black yellow

       Example 2 entries are:
	      color black  = #000000
	      color green  = #008000
	      color yellow = #ffff00
	      color blue   = #0000ff
	      color white  = #ffffff
	      color red    = #ff0000
	      color orange = #ffa500
	      color tan    = #d2b48c

	      user unconfined_u = #ff0000 green
	      role unconfined_r = red #ffffff
	      type unconfined_t = red orange
	      user user_u	= black green
	      role user_r	= white black
	      type user_t	= tan red
	      user xguest_u	= black yellow
	      role xguest_r	= black red
	      type xguest_t	= black green
	      user sysadm_u	= white black
	      range s0:c0.c1023 = black white
	      user *		= black white
	      role *		= black white
	      type *		= black white
