Why does it do that?

Why is the sky always paler within the rainbow rather than outside the rainbow.....

Great close up of the shroom! No idea about the rainbow, but someone here will know for sure ;-)

[Susan Wakely]

Great shrooms. I must study the sky the next time I see a rainbow.

[Delwyn Barnett]

What a good question, have no idea, but maybe it is something to do with the refraction of the sunlight? Nice macro of the mushroom.

Great pov. I've never noticed that with a rainbow. I'll have to check it out next time I see one.

Need to ask the QI Elves.... Great photo though

Beautiful details on the mushroom. Great question. I think this explains it: https://outreach.icfo.eu/project/why-is-the-sky-inside-the-rainbow-brighter-than-outside/

@shutterbug49 Thanks Debbie - I had a read of this and got the basic idea - refraction versus reflection - which makes sense. Always nice to know why things happen. Thanks for your suggestion. Cheers Rob

I don’t think I have ever noticed that before!

[KoalaGardens🐨]

ha physics is fascinating

[Granagringa]

Looks as if you've hit the gold at the end of the rainbow!

[Jane Pittenger]

No idea

Great pov and composition.

I always thought it had to do with how the light was traveling through the raindrops left over from the rain. I guess I was sort of right! Good catch!
