[R] can I plot a matrix of colors?

[dxc13]

Hi all,

I have a 36x14 matrix of hexadecimal coded colors (see attached file) that
was created with the following code:
cellcol[is.na(cellcol)] <- "#FFFF00"
#Aliceblue
cellcol[cellcol < 5] <- "#F0F8FF"
#Skyblue1
cellcol[cellcol >= 5 & cellcol < 20] <- "#87CEFF"
#Blue
cellcol[cellcol >= 20 & cellcol < 35] <- "#0000FF"
#Green3
cellcol[cellcol >= 35 & cellcol < 50] <- "#00CD00"
#Yellow2
cellcol[cellcol >= 50 & cellcol < 60] <- "#EEEE00"
#Orange2
cellcol[cellcol >= 60 & cellcol < 75] <- "#EE9A00"
#Red
cellcol[cellcol >= 75 & cellcol < 90] <- "#EE0000"    
#Firebrick
cellcol[cellcol >= 90] <- "#B22222"	

My question is, can I plot this matrix using image() or do the colors need
to be in a different format?
Thank you.
