The colours in the list can be uniquely identified by taking the characters at index 0 and 3, assuming modular indexing. This results in the following mapping:

rr -> red
yl -> yellow
ge -> green
bw -> brown
sr -> scarlet
bc -> black
or -> ochre
pc -> peach
ry -> ruby
ov -> olive
vl -> violet
fn -> fawn
la -> lilac
gd -> gold
cc -> chocolate
mv -> mauve
ca -> cream
cm -> crimson
sv -> silver
re -> rose
ar -> azure
lo -> lemon
rs -> russet
gy -> grey
pp -> purple
wt -> white
pk -> pink
on -> orange
be -> blue
