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.

SYNOPSIS

       ppmdither [-dim power] [-red shades] [-green shades] [-blue shades] [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap as input, and applies dithering to it to reduce the number of colors used down to the specified number of shades

       format suitable for color printers, use -red 2 -green 2 -blue 2.

OPTIONS

       -dim power    The  size of the dithering matrix.  The dithering matrix is a square whose dimension is a power of 2.  power is that power of
		     2.  The default is 4, for a 16 by 16 matrix.

       -red shades   The number of red shades to be used, including black; minimum of 2.

       -green shades The number of green shades to be used, including black; minimum of 2.
