Assign Row And Interior Color Directly To Array

I need to have 3 arrays for a column of data, the first holding each cell value, the second the Row number and the third, the Interior.Color.

Currently I am having to assign each row and interior colour to a variable with a | between each then use the split function on that variable to assign it to an array (no problem with each cell value as that can be assigned directly to an array.

Code:
For Each rC In Range("a2", Range("a" & Rows.Count).End(xlUp)).SpecialCells(12)
If sO = Empty Then
sO = rC.Interior.Color
Else: sO = sO & "|" & rC.Interior.Color
End If
If sR = Empty Then
sR = rC.Row
Else: sR = sR & "|" & rC.Row
End If
Next
c = Split(sR, "|")
v = Split(sO, "|")
x = Range("a2", Range("a" & Rows.Count).End(xlUp)).SpecialCells(12).Value

As there are over 10,000 rows involved loading the variables is taking a considerable amount ot time, whereas the direct loading of the value is very fast. So I want to be able to load all arrays directly.

I have tried various methods to get Row and Interior.Color to load directly into arrays c and v but without success so far.
