Nos.18 and 19 are both colour studies for the same commission (no.20). Turner has used the identical size and type of for each study and has positioned his images in exactly the same way on the two sheets. However, he has experimented with different colour schemes, no.18 being much lighter and brighter, with a greater emphasis on primary colours. In that work the is also much more fully resolved and both Kaub and Burg Gutenfels are now clearly visible.
