Color scheme of hydrophobicity

Rose (1) Kyte and Doolittle (2) Wolfenden (3) Janin (4)
First group C I,V,L G,I,L,V,A C Blue
Second group F,I,V,L,M,W F,C,M,A F,C,M I,V,L,F,M,A,G,W Aqua
Third group H,Y,A,G,T G,T,S,W,Y,P T,S,W,Y H,S,T,P,Y,N,D,Q,E green
Fourth group S,P,R,N,Q,D,E H,N,Q,D,E,K N,K,Q,E,H,D R Yellow
Fifth group K R R K Purple

The rank of hydrophobicity decreases going down the column.
