Dear all,

I have a question: what word or phrase describes sunlight that's reflected on your wall, sometimes in a rainbow.

I remember a.word.a.day many years ago that 'worded' this and it wasn't:

[list]
[*]reflection
[*]light play
[*]light manifestation, or
[*]something with prism

Thank you very much in advance for you help!
