High ceiling

I have been processing old photos today, as I have for the last few days, and I can no longer see colour accurately. I am going to take my exhausted visual cortex to bed where I hope I don't dream in pictures.
(This is not an old one - it appeared on the wall beside me and should have been a prompt to go out while the sun was shining. Next time I looked up it was dark.)
