If it's uncomfortable because it's sagging too much, lace the sides together with shoelace, and then tighten the tension bolt slightly. It should help dramatically.

The leather lace (lesson: don't use leather lace) on my saddle broke in the middle of a tour, and the saddle became unbearble until I laced it with a bit of discarded nylon chord I found on the side of the road.

As for the colour, you'll have to wear black shorts for a while.
