The light source can play havoc with the true colour. I left a green LHS in the.covered parking area at the Toronto airport for a few days, I kept a note of the level and area. When I returned I went there and could not see the green car in that area, I thought I must have written the level down wrong, so I looked on the level above and below. The area was just by the exit to the bridge to the terminal so that was easy to remember.
After 15 minutes I was back to square one, l saw a blue LHS and went over to it, it was my car but it looked like it had a respray.
The fluorescent lights changed the colour to appear the blue like my wife’s Concorde.
The colours and the cars may be the opposite of what I have written as this was in the late1990’s some time.
