Tomatoes come in many colours. I'm growing two varieties of yellow.
"Pick ripe, nearly ripe and mature green fruits before the possibility of frost. Remove long stems to prevent them from piercing each other. Store tomatoes in cardboard or wooden boxes, 1 to 2 layers deep, in a cool moderately humid room. Cover the boxes with newspaper as tomatoes need darkness to ripen.. Check the toms every day and remove the ripe ones.
As tomatoes ripen, they naturally release ethylene gas, which stimulates ripening. To speed up the ripening process put a ripening tomato, apple or banana in the box with green tomatoes. To slow the ripening process and give yourself an extended harvest store some tomatoes, covered in cardboard boxes, in a cooler location".
