Click one cell and change all cells of the same color - excel

Question

I'm currently working on a calendar where some days (each separate cells) have green, blue and others red backgrounds
I would like to be able to click one cell in the given range (one day in the calendar). If that cell has a specific background color, I would like all other cells in that range that are the same color to change and the text to be bold.
Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
Cancel = True
Dim cell As Range
Dim Rng As Range
Set Rng = ActiveWorkbook.Sheets("Tickets").Range("N11:AW20")
For Each cell In Rng
If Target.Interior.ColorIndex = 37 Then
Target.Font.Bold = True
End If
Exit For
Next cell
End Sub
So far the text of the Target cell changes to bold but not the rest of the cells in that range.
How can I get excel to scan the rest of the range and apply the changes?
PS: Originally I would have preferred triggering the macro when hovering over the cells but I couldn't find anything to do so.
Here is the file with the calendar to give you a better idea of the whole thing.

Answer 1

If you put this code into the module for the sheet with the calendar, it should activate each cell in the calendar range that has the same background color as the current selection.
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim rngCalendar As Range
Set rngCalendar = Range("N11:AW20")
If Not Intersect(Target, rngCalendar) Is Nothing Then
SpeedUp True
rngCalendar.Font.Bold = False
Dim cel As Range
For Each cel In rngCalendar
If cel.Interior.ColorIndex = Target.Interior.ColorIndex Then
cel.Font.Bold = True
End If
Next cel
SpeedUp False
End If
End Sub
Private Function SpeedUp(ByVal toggleOn As Boolean)
With Application
.Calculation = IIf(toggleOn, xlCalculationManual, xlCalculationAutomatic)
.ScreenUpdating = Not toggleOn
.EnableEvents = Not toggleOn
End With
End Function

Answer 2

The problem is that your loop doesn't actually do anything to the cell it's in.
You could change it into something like this
Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
Cancel = True
Dim cell As Range
Dim Rng As Range
Set Rng = ActiveWorkbook.Sheets("Tickets").Range("N11:AW20")
If target.Interior.Colorindex = 37 then
For Each cell In Rng
If cell.Interior.ColorIndex = 37 Then
cell.Font.Bold = True
End If
Next cell
End if
End Sub

Answer 3

I think it should help :)
Dim cell As Range
Dim Rng As Range
Dim status As Integer
Set Rng = ActiveWorkbook.Sheets("Tickets").Range("N11:AW20")
For Each cell In Rng
If Target.Interior.ColorIndex = 37 Then
Target.Font.Bold = True
status = 1
Exit For
End If
Next cell
If status = 1 Then
Rng.Interior.ColorIndex = 37
Rng.Font.Bold = True
End If
