“Enough of invisibility, silence, timidity, defensiveness, guilt! An invisible, silenced man was an empty space into which others could pour their prejudices, their agendas, their wrath. The fight against fanaticism needed visible faces, audible voices. He would be quiet no longer. He would try to become a loud and visible man.”

“A man is not idle because he is absorbed in thought. There is visible labor and there is invisible labor.”

“Grey has no agenda. . . . Grey has the ability, that no other colour has, to make the invisible visible.”

“Not everyone has a voice. Many outsiders cannot speak through walls, and, as a consequence, they become silent and invisible. Some give up their voices willingly. Others cannot face the ferocious silence of their lives; so they replace their genuine voices with incomprehensible shrieks of rage. They bombard the wall with wrath or batter it with explosives. The silence is broken by their rage, but nothing changes. They remain outsiders who are desperate to be allowed into the world.”

“Visible things can be invisible. However, our powers of thought grasp both the visible and the invisible – and I make use of painting to render thoughts visible.”

“It would be too easy to say that I feel invisible. Instead, I feel painfully visible, and entirely ignored.”
