Excel VBA

Color Rows by Criteria

Since it is almost 5K rows, I decided I wanted to color the rows with a specific color based on the year.

My list is complete from year 2000 to date (except for a short period where I lost access to some files in a move to new PC).

Sub ReColorSnapShot() 
    'ARB 12/02/2020
    '+-------------------------Unlock SNAPSHOT,set color scheme by Year, close and report------------------+
    '+-----------------------------------------------------------------------------------------------------+
    Dim Ranger  As String
    Dim LastCol As Long, lastRow As Long
    Dim SortRanger As Variant
    Dim C   As Long
    Dim H   As Long
    Dim Quo As String
    Dim YearNm As Variant, RGBnm As Variant
    Quo = Chr(34)
    Application.ScreenUpdating = True
    Sheets("SnapShot").Activate
    ActiveSheet.Unprotect
    lastRow = Range("L99999").End(xlUp).Row
    LastCol = 12  'Selection.End(xlToRight).Column
    Range(Cells(2, 1), Cells(lastRow, LastCol)).Select
    Selection.Interior.ColorIndex = False
    Cells(2, 1).Select
    YearNm = Array("2000", "2001", "2002", "2003", "2004", "2005", "2006", _
        "2010", "2011", "2012", "2013", "2020", "2021")  'omit 1900; make list of years
    RGBnm = Array(RGB(153, 204, 255), _
        RGB(131, 241, 123), _
        RGB(255, 153, 255), _
        RGB(255, 255, 0), _
        RGB(250, 191, 143), _
        RGB(205, 216, 176), _
        RGB(153, 204, 0), RGB(204, 255, 204), RGB(102, 204, 255), RGB(255, 204, 153), RGB(204, 192, 218), _
        RGB(207, 183, 255), RGB(93, 174, 255))    Each color is full RGB instruction
    For H = 0 To UBound(YearNm)	'Read array first to get Year
    SortRanger = RGBnm(H)		'Hold RGB current
    For C = 2 To lastRow		'Range
        
            If Cells(C, LastCol).Text = YearNm(H) Then	Does year match?
                If C Mod 2 = 0 Then		Check whether even numbered row
                Sheets("SnapShot").Range(Cells(C, 1), Cells(C, LastCol)).Interior.Color = SortRanger
                
            Else
                Sheets("SnapShot").Range(Cells(C, 1), Cells(C, LastCol)).Interior.ColorIndex = False
		'No color if odd numbered row 
                End If
            End If
            Next C
        Next H
        Cells(C - 20, 1).Select
        ActiveSheet.Protect
        MsgBox "Exhausted Year array", vbInformation, "H"
    YearNm = 0
    RGBnm = 0
    C = 0
    
End Sub
