How does Nikon d5 100 feel and look? Also, does the bright color of d5 100 affect the later revision?

Personal appearance feels better than Canon's, small and steady.

There are several aspects to feel, and the most important is the sense of grip and control, which can only be said to be worthy of its price, that is to say, the camera bought with money feels like this, which is more than enough.

Don't worry about color at all. Believe in the omnipotent PS. Generally, there is not much loss in adjusting the color of RAW photos in a small range, and it is easier to adjust the color for the scene. Portrait needs a little work. After all, Canon's elegant style is already the benchmark in portraits, but if you have a deep PS foundation, these are not things.
