Lennon's work on his Colour Collections led him to focus on single paintings, what he calls 'lenses'. In 2007 he commented 'Liquid/solid, liquid acrylic, solid acrylic, reflective, transparent, etc. They reflect the room - not like the traditional lens into another world. I like the way the metal makes the paint react - like the bone, the fleshiness of the paint on it' (see Awake! Absolutely. Awake', Ciáran Lennon, In Conversation, Stoney Road Press, May 2007, p. 98).
