Alternating text color of excel cell items after each space?

Question

Hello. I have a script that emails a table of info which works fine and that looks like this:
name, samaccountname, date, memberof
In the email table I was able to have it do a line break on each space so that the memberof groups are on on separate lines for easier reading.
Well I've been wanting to send the data to store in a csv sheet as well. I can get it going in there but for the member of column it puts in memberof1  memberof2  memberof3 etc etc on one line. The CNs OUs etc are all removed and its just the group
names separated by spaces. Works but a little hard to read.
I was thinking maybe there was a way to open the excel file for writing and on that one column have it alternate text colors using the space as the delimiter? Everything would be easier to read that way. Is this possible ?
Thanks

Thanks. I did look at that and have this so far. Im  just trying to echo it out right now, but Im guessing that somehow in the foreach ($item in $groups) I need to create an array or something? Then Id want to apply one color to each item in the array.
Ive tried several different combinations and was trying $item.spli(" ") but it always comes back looking the same.
So right now $item echos like this
Group1  Group2  Group3  Group4  Group5
Id just want to alternate each space delimited item one of two colors. Then take those appened colors of each item and write it back to the cell that I read it from in the column so that its easier to read. Is this even possible?
$objExcel = new-object -comobject excel.application 
$objExcel.Visible = $True
$ExcelFilesLocation = "c:\"
$UserWorkBook = $objExcel.Workbooks.Open($ExcelFilesLocation + "groups.csv")
$UserWorksheet = $UserWorkBook.Worksheets.Item(1)
$intRow = 2
Do {
 # Reading the first column of the current row
 $groups = $UserWorksheet.Cells.Item($intRow, 4).Value()
 foreach ($item in $groups)
 $regex = [regex] "\s"
 $split = $regex.split($item)
 Write-Host $split
 # Move to next row
 $intRow++
 While ($UserWorksheet.Cells.Item($intRow,1).Value() -ne $null)
