Tomatoes and coronets

I have been picking ripe tomatoes from the garden. Here are some of them on a white plate:

I wondered how close the 670nm coronet light was to tomato colour.

I put a coronet on a white plate and turned it on. This is the colour that come from the iPad camera:

In the kitchen, the red of the coronet looks pretty similar to the red of the tomatoes. The iPad camera makes the 670nm look pink. Most curious.

Here is the colour taken by Ron, who has real photographic skills and a real camera.

Much more tomato-like!
