Can you help me find the name of an artist if I describe their art to you?

I might be able to, but before I try, can you tell me what you’re looking for in an artist’s name?  You’re looking for an artist whose art is similar, or at least related, to the work I saw? Or you’re looking for an artist that’s well known, that’s reliable or is highly regarded?

-   Frank Auerbach
-   Edward Hopper
-   Robert Motherwell
-   Helen Frankenthaler
-   Barnett Newman
