Copy Yellow Cells in Row 2 of Sheet1 sequentially to Sheet2 - vba

Question

I want to search through cells in Row 2 of worksheet "In Motion". If a cell is highlighted yellow, I want to copy the entire column and paste it to worksheet "Dashboard". I want this to repeat to find every yellow cell in row 2 of "In Motion". I also want the columns to paste sequentially onto "Dashboard".
The code I have, which I've built partly from running macros doesn't work. It DOES copy the column of the first yellow cell it finds on "In Motion" and pastes to A1 of "Dashboard". But, it DOES NOT loop through all the cells in row 2. It just stops.
Also, I think if the loop were working, my code wouldn't effectively paste columns sequentially to "Dashboard". I think they'd all be pasting to A1.
Sorry for the noob quesiton. Help is greatly appreciated!
Sub AutoPopulateNew()
Dim C As Range
'Clear Dashboard
Worksheets("Dashboard").Activate
Worksheets("DashBoard").Cells.ClearContents
'Move to In Motion Sheet
Worksheets("In Motion").Activate
'Find and copy yellow highlighted cells
For Each C In Worksheets("In Motion").Rows("2:2")
C.Select
With Application.FindFormat.Interior.Color = 65535
End With
Selection.Find(What:="", LookIn:=xlFormulas, LookAt _
:=xlPart, SearchFormat:=True).Activate
ActiveCell.EntireColumn.Copy _
Destination:=Worksheets("Dashboard").Range("A1")
Next C
Worksheets("Dashboard").Activate
End Sub

You don't need to activate a sheet to write in it. I like to use RGB declaration of colors and(255,255,0) is yellow. You can use vbYellow instead too. To find out the RGB numbe of any color, select the cell, goto the buckets icon that colors the background, choose more colors and then custom to see the RGB numbers. This code will do that, edit as you need.
Sub AutoPopulateNew()
Dim i As Integer
Dim j As Integer
Dim count As Integer
Dim c As Range
'Clear Dashboard sheet
Worksheets("DashBoard").Cells.ClearContents
count = 1 'counts the cells with a matching background color
'Loop through the cells and check if the background color matches
For Each cell In Worksheets("In Motion").Rows(2).Cells
If cell.Interior.Color = RGB(255, 255, 0) Then
Worksheets("Dashboard").Cells(1, count).Value = cell.Value
count = count + 1
End If
Next cell
End Sub

Thanks Ibo for the help! The loop worked going through the highlighted cells.
For what it's worth, I ended up changing my approach to copying and pasting columns based on whether they are marked with "x" in a given row. Code is below if it helps anyone who stumbles here.
Sub AutoPopulateX()
Dim SingleCell As Range
Dim ListofCells As Range
Dim i As Integer
'Clear Dashboard
Worksheets("Dashboard").Activate
Worksheets("DashBoard").Cells.ClearContents
'Move to In Motion and Set Range
Worksheets("In Motion").Activate
Application.Goto Range("a1")
Set ListofCells = Worksheets("In Motion").Range("a2:ba2").Cells
i = 1
Set SingleCell = Worksheets("In Motion").Cells(2, i)
'Loop: search for xyz and copy paste to Dashboard
For Each SingleCell In ListofCells
If InStr(1, SingleCell, "x", 1) > 0 Then
Range(Cells(3, i), Cells(Rows.count, i)).Copy
Worksheets("Dashboard").Paste Destination:=Worksheets("Dashboard").Cells(1, Columns.count).End(xlToLeft).Offset(0, 1)
End If
Application.Goto Range("a1")
i = i + 1
Next SingleCell
'Clean up Dashboard
Worksheets("Dashboard").Columns("a").Delete
Worksheets("Dashboard").Activate
End Sub
