Couple of problems here.

First, Cells/Range doesn't have a Color property. For background color,
you need to use

Select Case Blatt.Cells(i, "K").Interior.Color

Second, XL can only display 56 colors at a time, so unless the RGB value
is one of the 56 colors in the color palette, it won't match. When you
assign an RGB value, XL tries to find the closest match. For instance,
when I enter this in the immediate window with the default palette:

Cells(1,"K").interior.Color = RGB(128,255,196)
?RGB(128,255,196)
12910464
?cells(1,"K").interior.color
13434828
?cells(1,"K").interior.color=RGB(128,255,196)
False

You're usually better off to use the .ColorIndex property.

third, Select Case is an 'expensive' control structure compared to
If...Then. It's probably appropriate for the outer Select Case
structure, but the inner one would be better off using If...Then:

Select Case Blatt.Cells(x, "C").Value
Case "critical"
If Blatt.Cells(i, "K").Interior.ColorIndex = 35 Then _
xAnz = xAnz + 1
Case "major"
yAnz = yAnz + 1
Case "minor"
zAnz = zAnz + 1
End Select

Or you could use the fact that VBA's True evaluates to -1:

Select Case Blatt.Cells(x, "C").Value
Case "critical"
xAnz = xAnz - (Blatt.Cells(i, "K").Interior.ColorIndex = 35)
Case "major"
yAnz = yAnz + 1
Case "minor"
zAnz = zAnz + 1
End Select

Next x


Cant i use . Color with this context to count lines with a certain rgb
background color ?


Thx alot
