With angry look one cuts prices for Matisse and others (10)

'matisse and others' is the definition.
I can't judge whether this definition defines the answer.

'with angry look one cuts prices' is the wordplay.
'with angry look' becomes 'lour' (I am not sure about this - if you are sure you should believe this answer much more).
'one' becomes 'i' (Roman numeral).
'cuts' means one lot of letters goes inside another (some letters cut their way into other letters).
'prices' becomes 'costs' ('cost' can be a synonym of 'price').
'lour'+'i'='louri'
'louri' put within 'costs' is 'COLOURISTS'.

'for' acts as a link.

Can you help me to learn more?
