How was Jonas's second experience with snow different from the first in The Giver?

The second time Jonas makes the sled ride, he is able to see that the sled is red.

The first time The Giver tells Jonas about snow, he has no idea what it is.  In Jonas’s community, they embrace the concept of Sameness.  This means that everything is the same as much as it can be.  They have controlled the climate and the environment, so that there is no weather and they have even eliminated hills.

The first memory Jonas receives is snow.  The Giver decides that snow is a good place to start, because it is so different from Jonas’s regular experiences.  It will really give him a window into the past.  Jonas has no idea what to expect, but loves his first experience.  The Giver sends him on a sleigh ride down a hill in the snow.

It was very startling; but he was not at all frightened, now. He was filled with energy, and he breathed again, feeling the sharp intake of frigid air. Now, too, he could feel cold air swirling around his entire body. He felt it blow against his hands where they lay at his sides, and over his back. (Ch. 11) 

Although Jonas knows that he may soon experience pain, he is exhilarated by his first experience.  Jonas has been chosen because he has the Capacity to See Beyond, and the ability to develop the wisdom to know how to use it.  He seems to know the concepts even though they are new to him.  The word “snow” comes to him, as well as the word “sled” and other words from the memory. 

Jonas knows that he is not allowed to discuss his training with anyone, but he realizes that he wouldn’t be able to.  They have no concept of snow or hills either, and he doesn’t know how to explain it to them.  It is too far outside their experiences. 

The second time Jonas experiences the snow, he also is learning that he is seeing color.  Jonas is dumbfounded by the experience, because although he has seen flashes of red in the apple, faces, and Fiona’s hair, he didn’t know what it was. 

This time it was not a fleeting impression. This time the sled had--and continued to have, as he blinked, and stared at it again--that same mysterious quality that the apple had had so briefly. And Fiona's hair. The sled did not change. It simply was--whatever the thing was.  (Ch. 12) 

This is the first time Jonas sees a color that stays.  From this he learns about the concept of color.  The Giver explains to him that there are more colors than just red, and then he begins to see all of the colors.  It is a more vivid, full life.  He doesn’t understand why the community would give it up, but The Giver explains that the community had to give up color with Sameness.
