A few decades ago I had this mysterious sunny morning with colors 10 times brighter than usual. I never managed to figure it out, now the only things I remember are that the curtains were open, the sun came in, I had a dark red box next to my bed that I must have looked at for 20-30 seconds because the color was so absurdly vivid, then I looked at a gold lamp on top and thought woah! The effect persisted for a while, everything in my house looked different. I've also noticed changes in my vision when sleeping in different places. What little I remember it sure fits your description. I might try hooking up a red heat lamp to a timer as an alarm clock to see what happens.
