The variety's I have are Cornio, Banana and Jalepeno - The purple chili's are supposed to be purple when picked aren't they???

Due to the not so hot weather only a few have ripened to a nice red colour which have been picked and used/frozen.
Problem is while I know that when green they can be eaten and in some cases are hotter than when they turned to red, I would like some more if possible. Unfortunately I don't have a green house and with small children around I'm not particularly keen in bringing them into the conservatory....
Any suggestions on how to ripen them? Or should I stop moaning and just be grateful I've got any chili's this year!
