Pronunciation: 'iddeu'matik
Definition: [adj] of or relating to or conforming to idiom

idiom: (n) A speech form or an expression of a given language that is peculiar to itself grammatically or cannot be understood from the individual meanings of its elements.

'idiomatic' is a series of journals designed to be entered into the ISTD student assessment competition.

The RGB (Red, Green, Blue) brief specified that the series of journals must be linked in some way thematically and each journal would be printed in only one of the colours and black ink.

'idiomatic' is about idioms to do with colour, such as to see red, the green eyed monster and blue in the face.
