In the image, the affirmation  Nuova Suzuki Alto. 20 chilometri con un litro /New Suzuki Alto. 20 kilometres with one litre of gasoline, becomes denied from the background great red-clear writing  NON CI CREDO / I don't believe in it,  which occupies nearly all the field. The reading of this rebus becomes  NON (auto) CI CREDO / I don't believe in a car,   solved from the white writing  Nuova Suzuki Alto. 20 chilometri con un litro /New Suzuki Alto. 20 kilometres with one litre of gasoline.  

In the emotional non-dominant half-brain the writing in white becomes black and that in red becomes green. Moreover, there is  a meaning change, for which  NON CI CREDO  becomes CI CREDO / I believe in it. On the contrary overthrow  of the other affirmation can become Vecchia Suzuki Basso. Non 20 chilometri con un litro / Low  Old Suzuki. No 20 kilometres with one litre of gasoline or can give a not understandable result.

The CI CREDO / I believe in it,  of the emotional half-brain, which occupies a larger brain space, if it not confirms the overthrow on the contrary of the writing in black, confirms however the white writing  of the image, which  so receives either a rational confirmation and an emotional confirmation.

That is diabolic!
