Update. Absolutely no color change after four days of direct sunlight and the peppers are getting soft so I put them in the fridge. Also, Saturday I had bought a few additional and forgot about them, leaving them in the clear plastic produce bag that had been twistied closed, left on the kitchen counter. Tuesday, when discovered, one had become completely red except for the very tip and was still firm, two were partially red but were soft and beginning to mold and the other three were still completely green. One firm, the other two softening and a wee bit moldy. I think I'll have to try the brown paper bag thing next.
Oh, also, the (clear) plastic bag was in direct sunlight in the afternoon as it was next to a window - I wonder if the light had anything to do with it?
After a few more days on the counterfour of the peppers that had been the plastic bag were ripened completely with only a few bad spots. The peppers in the paper bag are beginning to color and so far are just drying a little and not molding. Here's a pic of the "accidental" peppers (the green ones are fresh and all were grilled last night):
I was wondering the same thing but with one of those dessicant thingies...and they sat on the counter under a west facing window and got plenty of afternoon light.
