Beginning of Color

Jonas has received some amazing and one a little bit hurtful memory. He got the memory of Sunshine and Snow and what it's like to be on a sled and go down a hill. That little bit hurtful memory was a sunburn which he was interested in. The next day when he was with Fiona and she walked though the entrance doors something about her hair changed not the shape but the color. He was able to see the color red. I think that if I was Jonas this would be such and amazing experience and I would be so amazing by all this. Why would take away such beautiful colors?
