Highlighting specific column in cat/grep

I have a large * delimited text file and need to highlight specific columns on specific lines. The file looks similar to this:

Code:
ABC*01*00*01*00000 000000    *00000  000000    *35*0*0*0*0*20000*0*0*1*0000*00*4*0*3*0*0*1*0*  *35*0000*001*4*1OT2*0148*0*0*0*0*0*0*6A7801B0**TEST1
ABC*02*00*01*00000 000000 000000 000000    *00000 000000     *35*0*0*0*0*0*0*0*1*0010*00*4*0*0*0*0*1*0*  *35*0000*001*4*1OR2*0148*0*0*0*0*0*0*6A7701B0**TEST2

Is there any way of highlighting a specific column, so, for example, I get this:
Code:
ABC*01*00*01*00000 000000    *00000  000000     *35*0*0*0*0*20000*0*0*1*0000*00*4*0*3*0*0*1*0*   *35*0000*001*4*1OT2*0148*0*0*0*0*0*0*6A7801B0**TEST1
ABC*02*00*01*00000 000000 000000 000000    *00000 000000      *35*0*0*0*0*0*0*0*1*0010*00*4*0*0*0*0*1*0*   *35*0000*001*4*1OR2*0148*0*0*0*0*0*0*6A7701B0**TEST2

Unfortunately the values may be different, so I can't use egrep --color, or, the value may occur more than one in the line - eg one of the 0's.

Thanks in advance

NAME
pr - print file SYNOPSIS
pr [ option ... ] [ file ... ] DESCRIPTION
Pr produces a printed listing of one or more files on its standard output. The output is separated into pages headed by a date, the name of the file or a specified header, and the page number. With no file arguments, pr prints its standard input. Options apply to all following files but may be reset between files: -n Produce n-column output. +n Begin printing with page n. -b Balance columns on last page, in case of multi-column output. -d Double space. -en Set the tab stops for input text every n spaces. -h Take the next argument as a page header (file by default). -in Replace sequences of blanks in the output by tabs, using tab stops set every n spaces. -f Use formfeeds to separate pages. -ln Take the length of the page to be n lines instead of the default 66. -m Print all files simultaneously, each in one column. -n Number the lines of each file. -on Offset the left margin n character positions. -sc Separate columns by the single character c instead of aligning them with white space. A missing c is taken to be a tab. -t Do not print the 5-line header or the 5-line trailer normally supplied for each page. -wn For multi-column output, take the width of the page to be n characters instead of the default 72.
