The red color of tomatoes won't form when temperature are above 86oF, & in extremely hot areas, disappearing tomatoes on the vine may give them a yellowish ginger look. In this case, picking them within the pink stage and leting them ripen indoors in cooler temperature is a good conception.
Tomatoes need temperature, not light, to ripen, so there's no obligation to put them on a sunny windowsill. Place them out of direct sunlight -- even in a poorly lit cupboard -- where the heat is 65 to 70F.

If your outdoor temperature is below 86F & above 54F, you should permit the tomatoes ripen on the vine, which increases their lycopene content
