No, I err about the painter (6)

I believe the answer is:

renoir

(Other definitions for renoir that I've seen before include "Pierre Auguste ---, painter; Jean ---, film-director" , "French artist" , "French Impressionist, or his film director son" , "film maker" , "Pierre-Auguste -, French Impressionist painter" .)

I've seen this clue in The Irish Times and the Irish Times (Simplex).
