lattice and legend

I use lattice package to produce a bar chart. I set my.kolor for bars and
it displays properly but I have a problem with legend color. It behaves as
if I didn't set my.colors - the colors differs. How to work it out?     

barchart(Counts ~ Purchase | Products , data = my.data, groups = Model,
col=my.kolor,horizontal=FALSE,layout=c(1,4),
auto.key=list(rectangles = TRUE, space = "bottom"),scales = list(y =
"free"))

Searching for "barchart legend color" gives about  20 references. Please use
data sets that are reproducible, not your private data, for example

library(lattice)
col= c("red","green") 
barchart(yield ~ variety | site, data = barley,
         groups = year, layout = c(1,6),
         col= col,
         auto.key=list(rectangles = TRUE, space = "bottom",col=col)
         )
