Well, obviously I prefer gas cooking over electric, at least for the range top. For the oven, I prefer electric. For the broiler, gas. It does get a bit complicated, lol.
Robert, your decision to go with the pink makes sense, since that one is in much better working order and will need less done to it to get it ready for use. The yellow as a "back up" is good too.
I haven never seen yellow appliances as very common. Of course I'm not counting the very popular Harvest and Harvest Gold colors as yellow, per se. I like the bright sunshiny yellow of that range, and agree that it would look just as good in that kitchen as the pink one (you do have a yellow accent wall near it as well).
Personally I wouldn't have a pink appliance. Just not my taste. Pink bathroom, OK if it's vintage.
